9 Essential Portable Washing Machine Accessories for Full-Time RVers

Dragging a heavy bag of dirty laundry through a rainy campground to a sketchy laundromat is a rite of passage every full-time RVer quickly grows to detest. Installing a portable washing machine inside your rig offers ultimate freedom, but these units are rarely ready for the realities of mobile living straight out of the box. Building a reliable, leak-free system requires the right accessories to bridge the gap between residential convenience and RV system limitations.

Setting Up a Reliable and Efficient RV Laundry

Transitioning from campground laundromats to an onboard washing machine is a game-changer for full-time travelers. However, RV plumbing, electrical grids, and floor plans are not built like sticks-and-bricks laundry rooms. Standard portable washers require careful management of water pressure, drainage routes, and structural vibrations to prevent catastrophic leaks or rig damage.

Setting up a mobile laundry system requires understanding how your rig handles sudden water flow. You must balance the incoming pressure from campground spigots with the drainage capacity of your grey water holding tank. Planning your setup around these system limitations keeps your rig dry, quiet, and functional.

By choosing high-quality, task-specific accessories, you turn a loud, rattling appliance into a smooth-running utility. Investing in solid connections, proper filtration, and secure tie-downs ensures your washing machine operates efficiently without compromising your mobile home’s structural integrity.

Faucet Adapter – Camco Brass Quick Connect Fitting

The intake hose of a portable washing machine needs a reliable connection to your RV’s indoor plumbing, usually at the kitchen or bathroom sink. Threading and unthreading plastic hose connectors onto your metal faucet threads every single laundry day quickly strips the threads, leading to high-pressure leaks. A dedicated quick-connect fitting solves this by allowing you to attach and detach the water line in less than two seconds.

The Camco Brass Quick Connect Fitting is the ideal choice for this connection because of its lead-free solid brass construction. Unlike cheap plastic alternatives that warp under hot water or crack under pressure spikes, this brass fitting maintains a watertight seal. The pull-down collar mechanism utilizes a durable internal ball-bearing design that prevents accidental disconnections when the wash valve snaps shut.

• Material: Lead-free solid brass
• Thread Size: Standard garden hose thread (GHT) to quick-connect
• Best For: Frequent temporary setups at kitchen or bathroom sinks
• Incompatible With: Non-standard designer or pull-out spray faucets

Before buying, verify your faucet’s aerator thread size, as you may need a small dual-thread adapter to bridge the gap between the Camco fitting and your specific sink. This adapter is perfect for RVers who store their machine in a closet and set it up by the sink for weekly laundry days. It is not necessary if you have a dedicated utility closet with permanent plumbing hookups.

Sediment Filter – Camco TastePURE RV Water Filter

Campground hookups are notorious for delivering water loaded with fine sand, rust particles, and mineral scale. If this sediment bypasses your hose and enters your portable washing machine, it can clog the internal solenoid intake valves, causing them to stick open and flood your rig. An inline sediment filter catches these contaminants at the source, protecting your washing machine’s delicate mechanical parts.

The Camco TastePURE RV Water Filter is a highly effective line of defense due to its 20-micron sediment barrier and granular activated carbon design. It mounts directly to your exterior fresh water hose, filtering all incoming water before it ever enters your RV’s internal plumbing network. The wide-body design ensures that water flow remains strong enough to fill your washing machine quickly without triggering low-pressure error codes.

• Filtration Level: 20 microns
• Media Type: Granular Activated Carbon (GAC) with KDF to prevent bacteria growth
• Lifespan: Up to 120 days of continuous use
• Connection: Standard 3/4-inch garden hose threads

Keep in mind that this filter reduces pressure slightly as it fills with debris, meaning you must replace it regularly to maintain fast washer fill times. This is an essential accessory for boondockers and RVers who frequent older campgrounds with outdated well systems. It is less critical if you only park at modern resorts with advanced municipal water filtration systems.

Drying Rack – Honey-Can-Do Gullwing Drying Rack

Most portable RV washing machines use a spin-dry tub rather than a heated tumble dryer, which extracts bulk water but leaves clothes damp to the touch. A durable, space-efficient drying rack is essential for finishing the job without turning your RV cabin into a humid, cluttered mess. The ideal rack must provide maximum hanging space while folding down to a slim profile that fits into tight storage compartments.

The Honey-Can-Do Gullwing Drying Rack stands out because of its versatile, multi-position design that offers up to 46 linear feet of drying space. The steel support bars are strong enough to hold heavy, wet denim without bending or tipping over. Its unique gullwing design allows you to adjust the wings upward for long garments or lay sweaters flat across the center mesh shelf.

• Open Dimensions: 57″ L x 22″ W x 37″ H
• Folded Depth: 3 inches
• Material: Powder-coated steel and heavy-duty plastic joints
• Features: Dedicated shoe drying pegs and a flat sweater mesh area

When fully expanded, this rack requires a dedicated footprint inside your living space or outside under your awning. Because of its size, it is best suited for travel trailers and fifth wheels with open floor space, and it may be too large for compact camper vans. It is perfect for those who wash full loads of heavy cottons, but overkill for solo travelers who only wash lightweight synthetics.

Vibration Pads – Revcoo Heavy Duty Isolation Pads

Portable washing machines rotate at high speeds during the spin cycle, creating intense kinetic energy that can rattle thin RV floors and shake cabinet walls. Left unchecked, these vibrations can loosen your rig’s plumbing joins, damage delicate electronics, and make working or sleeping inside the coach impossible. Heavy-duty isolation pads absorb these kinetic forces before they transfer to your RV’s chassis.

The Revcoo Heavy Duty Isolation Pads are designed with a dual-material construction, featuring a hard rubber base and a dense polyurethane top layer. This combination deadens structural noise and dampens up to 94.7% of all vibrations. The deep recessed cup on top accommodates the feet of standard portable washers, while the micro-grip pattern on the underside prevents the machine from “walking” across slick laminate or shower floors.

• Material: High-density rubber and polyurethane
• Pack Size: 4 individual pads
• Height Increase: Adds approximately 1 inch to machine height
• Compatibility: Universal fit for most portable washer feet

Adding these pads raises the height of your washing machine by an inch, so ensure you have enough vertical clearance if your machine sits under a low countertop. They are a must-have for anyone placing a washing machine on a hollow slide-out floor or inside a lightweight closet. They are less necessary if your washer sits on a thick, carpeted floor or directly on a concrete patio outside.

Drain Support – Camco Sidewinder Sewer Hose Support**

When draining your washing machine, the internal pump pushes water out at a high velocity. If your main exterior sewer hose is resting flat on the ground, the sudden rush of soapy water can pool, creating backpressure that slows the drain cycle and leaves dirty water inside your washer’s tub. A sloped hose support uses gravity to ensure smooth, rapid drainage from your rig’s outlet directly to the campground sewer tap.

The Camco Sidewinder Sewer Hose Support features a sturdy, accordion-style plastic frame that curves easily around obstacles while maintaining a constant downward slope. The deep cradles hold your sewer hose securely in place, preventing the hose from kicking or shifting when the washing machine’s high-volume drain pump kicks on. It resists wind and UV damage, making it a reliable fixture for long-term camp stays.

• Available Lengths: 10, 15, and 20 feet
• Material: Lightweight, rust-resistant plastic
• Design: Flexible accordion style with snap-fit hinges
• Storage: Compresses down to a compact bundle for travel days

Ensure you select a length that matches your primary sewer hose to avoid leaving unsupported sections where water can pool. This accessory is crucial for RVers parked on uneven gravel or dirt campsites where maintaining a proper downhill slope is difficult. It is not needed if you always drain your portable washer directly into an indoor shower pan or utility sink.

Pressure Regulator – Renator M11-0660R Brass Valve

Campground water systems often suffer from unpredictable pressure spikes that can easily exceed 100 PSI (pounds per square inch). Portable washing machines are built with lightweight plastic internal water valves designed to handle a maximum of 50 to 60 PSI. An unregulated water surge can rupture these thin internal lines, causing a hidden leak inside your walls or flooding your living area.

The Renator M11-0660R Brass Valve is a premium, lead-free brass regulator that allows you to monitor and adjust your water pressure with precision. The oil-filled pressure gauge is easy to read and dampens needle vibration for accurate adjustment under flow. It is built to withstand high input pressures while maintaining a steady, safe output flow to protect your washer’s delicate solenoids.

• Material: Lead-free brass (C46500)
• Adjustable Range: 0 to 160 PSI (preset to a safe 45 PSI)
• Connection: 3/4-inch NH thread
• Gauge: Oil-filled pressure gauge

To maintain adequate water pressure to fill your machine efficiently, you must clean the small inlet stainless steel screen filter inside this valve periodically. This regulator is a non-negotiable safety tool for any RVer connecting to city water hookups at variable campgrounds. It is unnecessary if you run your washing machine using water exclusively pumped from your RV’s onboard fresh water tank.

Laundry Basket – SAMMART Collapsible Plastic Hamper

Standard rigid laundry baskets are incredibly bulky and difficult to store in the limited cabinet space of a travel trailer or camper van. Because space is at a premium, every item on board should ideally collapse or serve multiple purposes. A collapsible hamper keeps your dirty laundry organized and out of sight without permanently consuming valuable floor space.

The SAMMART Collapsible Plastic Hamper features a clever accordion design made of durable thermoplastic rubber (TPR) and heavy-duty plastic. It pops open to a generous 30-liter capacity for holding a full load of laundry, then collapses flat to less than three inches in height. The sturdy, non-slip handles make carrying heavy, wet loads from your machine to the drying rack comfortable and secure.

• Open Dimensions: 22.5″ x 17.5″ x 10.5″ H
• Collapsed Height: 3.1 inches
• Material: BPA-free plastic and flexible TPR
• Capacity: 30 Liters (8 gallons)

The flexible rubber joints can stiffen when exposed to freezing winter temperatures, requiring a firm press on a flat surface to expand or collapse. This space-saver is ideal for small travel trailers, class B motorhomes, and truck campers where closet space is highly limited. It may be less critical if you own a luxury fifth wheel with a dedicated laundry room and ample cabinet storage.

Detergent Sheets – Earth Breeze Eco Sheets Fresh Scent

Traditional liquid laundry detergents are heavy, messy, and prone to spilling inside your cabinets during bumpy travel days. Liquid jugs also take up valuable cabinet space and add unnecessary weight to your cargo limits. Additionally, many standard detergents contain harsh chemicals that can disrupt the delicate bacterial balance in your RV’s grey water tank or septic systems.

Earth Breeze Eco Sheets replace bulky plastic jugs with ultra-concentrated, biodegradable laundry sheets that dissolve completely in seconds. They perform exceptionally well in the low-water, cold-temperature cycles typical of portable RV washing machines. The thin cardboard packaging takes up about the same space as a small book, eliminating clutter and reducing plastic waste.

• Form Factor: Dry, pre-measured dissolvable sheets
• Ingredients: Hypoallergenic, paraben-free, and phosphate-free
• Package Weight: Less than 3 ounces for a 60-load pack
• Compatibility: High-efficiency (HE) and standard portable washers

For small, three-to-five-pound portable washer loads, you should tear a sheet in half to prevent oversudsing, which can overwhelm your machine’s drain pump. These sheets are perfect for eco-conscious RVers, boondockers looking to protect their holding tanks, and travelers focused on weight savings. They are less suited for those who prefer heavy, artificial perfumes or require industrial-grade chemical stain removers.

Mesh Lint Snare – Kieba Stainless Steel Lint Traps

Most portable washing machines utilize a simple gravity drain system that lacks a robust internal lint filtration screen. As a result, lint, pet hair, and clothing fibers are discharged directly into your RV’s grey water tank. Over time, this wet lint accumulates on your tank walls, wraps around your tank sensor probes (causing false readings), and clogs your main grey water dump valve.

The Kieba Stainless Steel Lint Traps are fine-mesh wire sleeves designed to slip over the end of your washer’s discharge hose. They capture hair and fibers before the wastewater enters your RV’s drain pipe or a sink basin. Constructed from rust-resistant stainless steel, these traps are highly durable and will not tear or blow off under high water pressure.

• Material: Rust-resistant stainless steel
• Inclusions: 12 lint traps and 12 securing ties per pack
• Length: 11 inches long to allow high flow as it fills
• Best Used For: Discharge hoses draining into sinks or tub basins

These metal traps must be checked and replaced or cleaned every few wash loads to prevent lint build-up from restricting water flow and causing a sink overflow. This accessory is absolutely essential for pet owners and RVers who wash fuzzy fabrics like fleece or wool. It is not necessary if your machine drains directly into a closed sewer standpipe equipped with an inline residential trap.

Managing Your Grey Water Tank Capacity While Washing

Portable washing machines are surprisingly thirsty, using anywhere from 10 to 20 gallons of water per load depending on your wash and rinse settings. In a typical RV with a 30-gallon grey tank, a single laundry session can easily fill your tank to maximum capacity. If you are not hooked up to a sewer connection, this can quickly lead to dirty water backing up into your shower pan.

To manage this, always check your tank levels before starting a wash cycle and plan your laundry days to coincide with hookup availability. If you are dry camping, you can minimize water use by running smaller loads, skipping extra rinse cycles, or manually adding water to the tub to control the exact volume used.

• Monitor Levels: Check your grey tank sensor before and after every load.
• Repurpose Water: Consider routing the discharge hose into a clean five-gallon bucket to use for flushing the toilet.
• Optimize Cycles: Use the “spin-only” setting to extract maximum water before draining, reducing the load on your holding tanks.

Securing Your Mobile Laundry Setup for Travel Days

An unsecured 40-pound washing machine can easily slide, tip over, or become a dangerous projectile during a sudden brake or on a bumpy mountain pass. Road vibrations can also cause the internal components to shift, or rattle the outer plastic casing until it cracks. Properly securing your machine before pulling in your slides is critical to protecting your appliance and your RV’s interior.

Start by fully draining any remaining water from the pump and internal hoses into a bucket or drain to prevent mold and stale water leaks. Coil the power cord and tuck the inlet and outlet hoses directly inside the washer drum to protect them from getting pinched or crushed by shifting cargo.

If your washer lives in the shower pan during travel, secure it using heavy-duty tension rods or ratcheting cargo straps anchored to secure tie-down points. If stored in a closet, wedge high-density foam blocks around the unit to absorb road shocks and prevent it from shifting against cabinet doors. Taking these precautions ensures your machine arrives at your next destination undamaged and ready for the next load.

Conclusion

Equipping your portable RV washing machine with the right support accessories transforms a potentially messy chore into a seamless, reliable routine. From protecting your plumbing with pressure regulators and brass quick-connects to managing dampness with a high-capacity drying rack, these tools keep your rig dry and quiet. Investing in this complete laundry setup allows you to enjoy clean clothes on your own schedule, leaving you more time to focus on the road ahead.
