Why You Need These Essentials Before Your First Trip

An RV is not just a vehicle; it is a rolling home with self-contained utility systems. Unlike a traditional house, where plumbing and electrical connections are permanent and hidden, mobile systems require manual setup at every new location. Without the proper interface accessories, connecting these systems to campground utilities is impossible, unsafe, or highly unsanitary.

Relying on campsite camp stores for these necessities is a risky and expensive gamble. These shops carry limited inventory, charge premium prices, and often stock low-grade accessories that fail after a few uses. Buying your core utility gear ahead of time ensures you have reliable, high-quality tools designed to protect your rig’s plumbing and electrical systems.

The right equipment also protects your financial investment. High water pressure can burst delicate interior PEX lines, and unstable campground power pedestals can instantly fry expensive onboard electronics. Spending a modest amount on protective accessories now prevents thousands of dollars in emergency repair bills later.

Sewer Hose – Camco RhinoFLEX 15-Ft Sewer Hose Kit

A reliable sewer hose is the single most critical accessory for any RV with waste tanks. Its primary job is to safely transport gray and black water from the RV’s waste outlet to the campground dump station without leaks, tears, or spills. Cheap, thin hoses can rupture under pressure, creating an unsanitary mess that ruins a trip instantly.

The Camco RhinoFLEX 15-Ft Sewer Hose Kit is the industry standard for durability and ease of use. Constructed from tough polyolefin and reinforced with steel wire, it holds its shape when bent or compressed. It features pre-attached swiveling bayonet fittings that lock securely to the RV outlet, along with a transparent elbow that allows the user to see when the tanks are completely clean.

• Material: 23-mil polyolefin reinforced with steel wire
• Compressed Length: 56 inches for easy storage
• Fittings: 4-in-1 translucent elbow adapter fits standard dump stations
• Compatibility: Works with all standard RV bayonet waste outlets

Before purchasing, measure the storage compartment on the RV. While this hose compresses tightly, it must still fit inside your bumper or storage tube. Always rinse the hose thoroughly after each dump, and store it with the end caps securely screwed on to prevent residual drips.

This kit is essential for anyone owning an RV with standard black and gray holding tanks. It is not necessary for those using dry-composting toilets or self-contained cassette toilet systems.

Water Regulator – Camco Brass Water Regulator

Campground water systems are notoriously unpredictable, with water pressure sometimes exceeding 100 PSI. RV plumbing systems, however, are typically rated for a maximum of 50 to 60 PSI. A water regulator sits between the campground spigot and your hose, acting as a barrier that reduces high incoming pressure to a safe, steady level.

The Camco Brass Water Regulator is a highly durable, solid-brass accessory that limits water pressure to a safe 40 to 45 PSI. Unlike cheap plastic regulators that crack under pressure or degrade in sunlight, this lead-free brass model handles heavy use while keeping drinking water clean and safe. Its simple, flow-through design ensures you do not lose volume while protecting your internal lines.

• Material: Lead-free brass (compliant with federal safety laws)
• Default Pressure Rating: 40–45 PSI
• Connection Size: Standard 3/4-inch garden hose threads
• Compatibility: Fits all standard city water spigots

Always connect this regulator directly to the campground spigot before connecting your hose. This setup protects both your drinking water hose and your internal plumbing from surging pressure. During freezing weather, disconnect the regulator to prevent trapped water from expanding and cracking the internal brass housing.

This regulator is a must-have for any RVer planning to use city water hookups at commercial campgrounds. It is unnecessary for boondockers who only rely on their onboard fresh water tank and internal 12-volt water pump.

Surge Protector – Progressive Industries EMS-PT30X

Campground power pedestals are exposed to harsh weather and heavy use, often resulting in reversed polarity, open neutrals, or sudden voltage spikes. Plugging an RV directly into a faulty pedestal can ruin the air conditioner, microwave, and onboard control boards. An electrical management system (EMS) acts as a smart gatekeeper, analyzing the power quality before allowing it into the rig.

The Progressive Industries EMS-PT30X goes far beyond a basic surge strip by constantly monitoring voltage, frequency, and wiring conditions. It features a digital display that scrolls through real-time voltage and amp draw, instantly shutting down power if conditions drop below 104 volts or rise above 132 volts. The unit is housed in a rugged, weather-resistant enclosure designed for outdoor use.

• Power Rating: 30-amp (also available in 50-amp as the EMS-PT50X)
• Surge Protection: 1,790 Joules
• Operating Temperatures: -40°C to 105°C
• Display: 3-digit LED screen displaying error codes and current status

When using this device, secure it to the pedestal lockbox with a cable lock, as these high-end units are common targets for theft. Ensure you purchase the correct amperage model matching your RV’s electrical service panel. Understanding the digital error codes helps troubleshoot campground wiring issues with park management before calling a mobile technician.

This unit is essential for anyone connecting an RV to public utility poles. It is not designed for off-grid rigs running purely on independent solar generators or small portable inverter generators.

Drinking Water Hose – Camco TastePURE 25-Foot Hose

Using a standard green garden hose to fill an RV’s fresh water tank introduces a strong, plastic chemical taste and potentially harmful contaminants. Dedicated drinking water hoses are manufactured without lead, BPA, or phthalates, ensuring the water remains clean and odorless. These hoses are easily identifiable by their bright blue styling.

The Camco TastePURE 25-Foot Hose uses heavy-duty, NSF-certified materials to deliver safe drinking water. It is reinforced with a high-tensile strength knit jacket that resists kinking and remains flexible in cold weather. The nickel-plated brass fittings are resistant to corrosion and provide a leak-free seal at both ends.

• Certification: NSF-listed, BPA-free, and lead-free
• Diameter: 5/8-inch inner diameter for optimal flow rate
• Length: 25 feet (ideal for most campsite layouts)
• Fittings: Heavy-duty, nickel-plated brass threads

Never use this hose for any task other than supplying fresh water to the RV. Keep it coiled and screw the male and female ends together when in storage to keep bugs, dirt, and mold out of the line. If camping in freezing climates, keep the hose drained or upgrade to a heated hose model.

This hose is mandatory for any RV setup utilizing campground fresh water hookups or filling an onboard tank. It is not needed if the rig is used strictly for dry camping with pre-bottled water.

Leveling Blocks – Camco Heavy Duty Leveling Blocks

Campground sites are rarely perfectly level, which causes more than just physical discomfort when sleeping. RV absorption refrigerators require a level surface to allow the cooling liquid to circulate properly; running them off-level can cause permanent cooling unit failure. Leveling blocks are placed under the low-side tires to raise the rig to a perfectly flat plane.

The Camco Heavy Duty Leveling Blocks feature a interlocking design that works like giant building blocks. Made from UV-stabilized, high-density polyethylene, they support heavy rigs without cracking under pressure. The bright orange color makes them easy to see when backing onto them, and the integrated carrying strap keeps them organized.

• Material: UV-stabilized resin construction
• Weight Capacity: Up to 40,000 lbs total
• Dimensions: 8.5″ x 8.5″ x 1″ per individual block
• Pack Size: 10 interlocking blocks with carrying strap

Always ensure the ground beneath the blocks is relatively flat and free of sharp rocks that could puncture the plastic. Avoid stacking them higher than four inches to maintain structural stability under the tire. Ensure the tire is fully centered on the block stack to prevent tread damage.

These blocks are ideal for travel trailers, fifth wheels, and camper vans without automatic hydraulic leveling jacks. Owners of high-end motorhomes with built-in auto-leveling systems can skip these, though they remain useful as pads under jack feet on soft soil.

Wheel Chocks – Maxxhaul 50011 Rubber Wheel Chocks

Once an RV is leveled, it must be secured to prevent rolling or shifting. This is especially critical for towable travel trailers and fifth wheels, which have no mechanical parking brake once disconnected from the tow vehicle. Heavy-duty wheel chocks lock the tires in place, providing peace of mind during windy days or heavy movement inside the rig.

The Maxxhaul 50011 Rubber Wheel Chocks are constructed from thick, durable rubber rather than cheap, lightweight plastic. They feature a ribbed, high-traction design that grips both the tire and the ground surface, preventing slippage on wet grass or gravel. An integrated rubber handle allows for quick placement and easy removal when packing up.

• Material: Heavy-duty, oil-resistant rubber
• Dimensions: 8″ x 4″ x 3.75″ per chock
• Weight: 3.8 lbs per pair
• Traction: All-weather ribbed surface pattern

Always place chocks snugly against both the front and back of the tires on both sides of the RV before unhitching from the tow vehicle. Storing rubber chocks in a sealed compartment can sometimes result in a strong rubber odor, so keeping them in an exterior storage bay is recommended.

These chocks are a safety requirement for all towable RVs, including travel trailers, pop-ups, and toy haulers. They are less critical for drivable class B motorhomes, which rely on the vehicle’s transmission park gear and emergency brake.

RV Toilet Paper – Scott Rapid-Dissolving Tissue

Standard residential toilet paper is designed for high-flow municipal sewer systems, meaning it does not break down easily in closed systems. In an RV, this thick paper quickly clumps together, leading to sensor malfunctions and blockages at the waste gate. Special rapid-dissolving tissue is designed to break apart immediately upon contact with water.

The Scott Rapid-Dissolving Tissue is engineered specifically for RV, marine, and septic systems. It is soft and absorbent, yet it dissolves four times faster than standard household toilet paper. This rapid breakdown prevents the dreaded “black tank pyramid” from forming beneath the toilet valve.

• Sheet Count: 231 sheets per roll (single-ply)
• Dissolving Speed: Specially formulated to break down in seconds
• Certifications: FSC certified, biodegradable, and septic-safe
• Packaging: Typically sold in 4-roll or 8-roll packs

To test your paper, place a single sheet in a jar of water and shake it; it should dissolve into fine particles within 30 seconds. Always use plenty of water when flushing to keep the paper moving smoothly through the system. Avoid using ultra-plush, multi-ply brands, even if they claim to be septic-safe.

This accessory is mandatory for any RV equipped with a standard black water holding tank and gravity-flush toilet. It is not necessary for dry-composting toilets or incinerator-style marine toilets.

Water Filter – Camco TastePURE Inline Water Filter

Campground water can contain high levels of sediment, rust, chlorine, and sulfur, which ruin the taste of coffee and leave mineral deposits in your water heater. An inline water filter cleans the incoming water supply before it enters your plumbing system. This protects your fixtures from clogs and ensures you have clean water for cooking, washing, and drinking.

The Camco TastePURE Inline Water Filter uses Granular Activated Carbon (GAC) combined with KDF media to inhibit bacteria growth while the filter is stored. It features a 20-micron sediment barrier that stops dirt and rust particles from entering the RV. The filter includes a flexible hose protector that reduces strain on the campground spigot connection.

• Filtration Rating: 20-micron sediment barrier
• Media Type: Granular Activated Carbon (GAC) and KDF
• Lifespan: Up to 3 months of continuous camping use
• Inclusions: Includes one flexible brass hose protector

Always flush the filter for 30 seconds before connecting it to your RV to clear out any loose carbon dust. Store the filter in a cool place when not in use, and cap the ends to prevent contamination. Replace the filter at the start of every camping season, or sooner if water flow rate decreases significantly.

This inline filter is perfect for casual weekend RVers wanting reliable, straightforward water filtration. Those living full-time or traveling through areas with severe water contamination may want to upgrade to a dual-canister system instead.

RV Power Adapter – Camco 30-Amp to 15-Amp Dogbone

Most RVs are wired for 30-amp or 50-amp electrical service, which cannot plug directly into standard 15-amp household outlets. An adapter allows you to plug your heavy-duty power cord into a standard household outlet, making it easy to prep your rig at home. This connection lets you run lights, charge house batteries, and cool down the refrigerator before a trip.

The Camco 30-Amp to 15-Amp Dogbone features a heavy-duty, flexible design that reduces physical stress on the outlet. Unlike flat “puck” adapters that overheat quickly under load, this dogbone adapter uses heavy-duty copper wire encased in a durable PVC jacket. It also features built-in power indicator lights and easy-grip handles for safe unplugging.

• Configuration: 15-Amp male plug to 30-Amp female receptacle
• Wire Gauge: 10-gauge heavy-duty copper wiring
• Jacket Material: Flame-retardant, UV-resistant PVC
• Handle Design: PowerGrip handle for secure finger placement

Do not attempt to run high-load appliances like your air conditioner or microwave while plugged into a 15-amp home outlet with this adapter. Doing so will trip your home’s breaker and can overheat the adapter plug. Use this connection strictly for charging batteries, running low-draw electronics, or pre-cooling the fridge.

This adapter is essential for RVers who store their rigs at home or plan to camp in driveways. If your RV is wired for 50-amp service, you will need a 50-amp to 15-amp dogbone adapter instead.

Tank Treatment – Happy Campers Organic Treatment

An untreated black water holding tank will quickly emit foul odors, especially during warm summer months. Tank treatments use natural enzymes and minerals to break down solid waste and toilet paper while neutralizing odor-causing bacteria. Keeping the tank treated prevents solids from sticking to the tank walls and keeps level sensors working properly.

Happy Campers Organic Treatment is a highly concentrated, biodegradable powder that eliminates odors instead of just masking them with perfumes. It remains effective in extreme temperatures and does not use harsh chemicals like formaldehyde, which are banned in many campgrounds. This formula keeps the tank clean and free-flowing without harming septic systems.

• Formulation: Natural mineral and enzyme powder
• Treatment Capacity: One scoop treats up to a 40-gallon tank
• Chemical Profile: Non-toxic, biodegradable, formaldehyde-free
• Package Options: Available in 18-dose tubs or larger bulk sizes

To use, dissolve one scoop of powder in a gallon of water and flush it down the toilet immediately after dumping your tanks. Always ensure there is a base of 2 to 3 gallons of clean water in the tank to allow the enzymes to activate. Avoid mixing this product with other chemical treatments, as they can deactivate the organic formula.

This treatment is highly recommended for all standard black water holding tanks. It is not suitable for dry-composting systems, cassette toilets, or portable camping toilets.

How to Test Your RV Systems Before Hitting the Road

Testing all of your RV’s systems in a controlled environment before your first trip is the best way to prevent campsite surprises. Set up a “driveway campout” at home, utilizing your new adapters and accessories to run through a full trial setup. This practice session allows you to spot issues, verify connections, and get comfortable with the gear without campground pressure.

+---------------------------------------------------------+ |                  PRE-TRIP CHECKLIST                     | +---------------------------------------------------------+ | [ ] Flush & sanitize fresh water lines                   | | [ ] Connect water regulator & check for hose leaks       | | [ ] Plug in EMS surge protector; verify voltage readings| | [ ] Test 12V battery charge & 120V outlet power         | | [ ] Verify propane lines are clear & appliances ignite  | | [ ] Double-check wheel chocks & leveling block placement| +---------------------------------------------------------+ 

Begin by sanitizing your water system and pressurizing the plumbing lines using your new drinking water hose and water regulator. Check every connection, faucet, and low-point drain for leaks, and run the water heater to ensure it functions on both propane and electric modes. Next, plug your EMS surge protector into your home outlet using your dogbone adapter to verify the system powers up and displays clean voltage.

Finally, practice leveling the rig on your driveway using the leveling blocks and securing the wheels with the rubber chocks. Open and close your slides, extend your awning, and run through the process of setting up and storing your sewer hose. Taking the time to master these steps at home ensures your first real campsite setup is a smooth and stress-free success.

Conclusion

Equipping your RV with these ten basic utility accessories ensures you can safely connect to any campground hookup with total confidence. By investing in quality gear before your tires hit the pavement, you protect your rig’s vital systems from damage and prevent unexpected delays. Pack your gear, test your connections, and enjoy the peace of mind that comes with being fully prepared for the road ahead.
