9 Best RV Sewer Hose Support And Leveling Gear For Full-Time RVers

Setting up camp for a long-term stay involves more than just plugging in your power cord and turning on the water. Without a reliable, gravity-assisted pathway for your rig’s wastewater, a simple chore can quickly devolve into a messy, unsanitary disaster. Investing in the right sewer hose support and leveling gear ensures that gravity works in your favor, keeping your site clean and your plumbing system functioning flawlessly.

Why Proper Hose Slope Matters for RV Wastewater Flow

RV holding tanks rely strictly on gravity to drain efficiently. When a sewer hose lies flat on the ground, wastewater pools in the low spots, creating pockets of standing liquid and solid waste. Over time, these pockets cause blockages, unpleasant odors, and backpressure that can rupture your hose connections during a dump.

To prevent these issues, campgrounds require a continuous, downward slope from the RV outlet to the sewer inlet—ideally a drop of one-fourth inch per foot. This steady decline allows solids and liquids to flow together smoothly without leaving residue behind. Without physical support to lift the hose over uneven ground, rocks, and grass, achieving this consistent angle is nearly impossible.

Beyond basic flow, leaving a hose directly on the ground exposes it to physical damage. Sharp gravel, stepping feet, lawnmowers, and wandering pests can easily puncture thin vinyl hoses. Elevating your line not only secures the gravity path but also isolates your expensive sewer hose from environmental hazards.

Accordion Hose Support – Camco Sidewinder 15-Foot

An accordion-style support is the bread and butter of quick RV setups, designed to cradle the sewer line and guide it over uneven terrain. It compresses into a tight footprint for storage and stretches out instantly to match the length of your hose. This prevents saggy loops that trap waste and ensures a straight, sloped trajectory.

The Camco Sidewinder 15-Foot model excels due to its lightweight, durable all-plastic design that won’t rust or corrode under harsh weather. It features a deep cradle design that holds the hose securely without the need for tie-down straps. The snapping hinges allow it to curve around obstacles easily, making it highly adaptable to cramped campsites.

• Extended length: Stretches up to 15 feet
• Storage footprint: Compresses to just 6 inches wide
• Material: High-density, rust-proof polyethylene

While it performs exceptionally on grass and gravel, very high winds can occasionally shift this lightweight plastic frame. Full-time RVers in stormy climates may need to anchor the ends with small stakes or weights to prevent shifting.

This support is perfect for travelers and full-time RVers who move frequently and value a rapid, hassle-free setup. It is not ideal for those parked permanently in freezing northern climates, where extreme cold can make thin plastic components brittle over time.

Flexible Hose Support – Valterra Slunky 15-Foot

Flexible metal or plastic-reinforced frame supports provide a highly adjustable slope over complex, bumpy terrain. They act as a flexible bridge, absorbing ground vibrations and compensating for sudden drops in elevation. Their main job is to maintain structural integrity while allowing you to snake the hose around trees or power pedestals.

The Valterra Slunky 15-Foot support stands out with its heavy-duty metal chains and plastic cradles, offering superior stability over purely plastic accordion models. It features built-in self-locking retaining straps that keep the hose secured to the cradles even during high-pressure dumps. The graduated design naturally creates a steeper slope from the RV to the drain hookup.

• Slope mechanism: Graduated height design
• Included accessories: Tie-down straps and storage handle
• Width: Wide cradles compatible with all standard 3-inch hoses

Because of the metal-reinforced linkages, this model is heavier and takes slightly more effort to expand and compress than all-plastic alternatives. Keep the metal hinges clean and dry before packing them away to prevent stiffness or surface rust over years of use.

This is the go-to choice for RVers who frequently camp on sloped, rocky, or uneven terrain where lighter plastic supports might tip over. It is less suitable for minimalist travelers with extremely limited storage bay space, as it is bulkier than simple plastic accordion designs.

Rigid Channel Support – Lippert Flow Down System

When parked at a campsite for weeks or months at a time, temporary accordion supports can sag over time under the weight of repeated dumps. A rigid channel system acts as a semi-permanent trough, providing rock-solid, straight-line support that eliminates any possibility of hose dipping. It elevates the hose completely off the ground, mimicking residential PVC plumbing.

The Lippert Flow Down System utilizes half-pipe plastic channels supported by adjustable metal legs to create a customizable, rigid highway for your wastewater. This system allows you to set precise heights for each section of the channel, overcoming dramatic drops or uphill obstacles near the sewer tap. Its high-quality, UV-resistant plastic channels protect the hose from intense sun exposure and physical impact.

• Adjustable height: Leg heights can be set individually
• System length: Includes four 30-inch half-pipe sections
• Material: Heavy-duty, UV-stabilized polymer

The primary trade-off here is the setup time, as adjusting each leg to the correct height requires a bit of trial and error during your initial arrival. It also takes up more storage space in your utility bay than compressed accordion models.

This system is highly recommended for stationary full-timers, seasonal campers, and those dealing with awkward sewer connections that require elevated routing. It is not practical for overnight travelers or quick-stop roadtrippers who do not want to spend fifteen minutes leveling a sewer line support.

Interlocking Log Support – Prest-O-Fit Prest-O-Log

Interlocking block or “log” supports offer a modular, highly stable platform for your sewer hose. Instead of relying on a flexible frame that can collapse sideways, these supports lock together to form a sturdy, flat-bottomed base. They are engineered to resist tipping, even when subjected to the sudden rush of water from a black tank flush.

The Prest-O-Fit Prest-O-Log consists of interlocking plastic segments that can be nested together to create varying heights and lengths. The unique design allows you to stack the “logs” to build a custom-sloped ramp that matches your specific site layout. Made from durable, UV-resistant plastic, they hold up exceptionally well under intense sunlight and heavy usage without cracking.

• Configurations: Custom lengths up to 15 feet
• Design: Interlocking segments with built-in slope guides
• Storage: Nested design reduces bulk in storage compartments

Note that because these are individual pieces, you must ensure they are clicked together securely on level ground to prevent them from separating under pressure. They perform best on relatively flat surfaces like concrete pads, asphalt, or hard-packed dirt.

It is ideal for RVers who prioritize wind resistance and structural stability over quick deployment. It is not the best fit for those who camp primarily on highly irregular, rocky terrain where flat-bottomed blocks cannot sit level.

Stackable Support Blocks – Camco Hose Support Blocks

Sometimes, standard long runs aren’t the issue; instead, you need localized elevation to clear a curb, a retaining wall, or a high campground sewer inlet. Stackable support blocks allow you to build customized piers under specific sections of your hose. They provide targeted lift right where you need it, preventing the hose from bunching or kinking at the hookup.

The Camco Hose Support Blocks are designed specifically for this structural duty, featuring curved tops that cradle 3-inch sewer hoses perfectly. They nest together compactly when not in use, taking up minimal space in your wet bay. Their bright color ensures high visibility, reducing the risk of accidental trips or run-overs by vehicles.

• Quantity: Typically sold in packs of 5 or 6
• Nesting feature: Saves space in utility compartments
• Compatibility: Works with all standard sewer hoses and other support systems

These blocks do not connect together to form a continuous bridge, meaning you will need a stiff hose or an accompanying channel if you plan to bridge long gaps between blocks. They require manual adjustment to ensure the slope remains downward toward the drain.

These blocks are excellent for RVers who already have a basic support system but need extra lift over obstacles, or for minimalists who only need short-run support. They are not a standalone solution for long, 15-to-20-foot spans over rough ground.

Modular Leveling Blocks – Tri-Lynx Lynx Levelers

Leveling blocks are primarily known for stabilizing your RV’s tires or jacks, but they are also incredibly versatile utility tools. In a pinch, they can be stacked like interlocking building blocks to support sewer hoses, water filters, or stabilizer legs. Keeping a multi-use leveling system on hand reduces the need to carry single-purpose plastic accessories.

The Tri-Lynx Lynx Levelers are the industry standard for modular utility blocks, boasting a high-strength, honeycomb design that handles extreme weight. You can stack them in a pyramid configuration to create a stable, elevated platform for your sewer hose elbow or inline macerator pump. They are incredibly tough, resistant to oil, dirt, and UV damage, and wash clean with a simple spray of water.

• Weight capacity: Up to 40,000 lbs (highly durable)
• Storage: Heavy-duty nylon carrying case included
• Material: Copolymer polypropylene

When using these for sewer lines, you will need to place a separate cradle or a piece of foam on top to keep the hose from rubbing against the hard plastic edges. Because they are flat on top, they do not naturally cradle a round hose without assistance.

This gear is perfect for space-conscious RVers who love multi-functional gear that can level a tire, support a jack, or elevate a sewer line. It is not a replacement for a dedicated, full-length sloped sewer support if you regularly deal with long sewer runs.

Extra-Long Hose Support – Camco Sidewinder 20-Foot

Large campsites or sites with poorly placed sewer inlets often require you to run multiple sewer hoses together, demanding a support system that can reach. A standard 15-foot support will leave your line sagging on the ground if you are forced to stretch your utility lines. An extra-long support ensures you can maintain a proper slope even when parked far from the hookup.

The Camco Sidewinder 20-Foot model offers the same durable, rust-proof plastic construction as its shorter counterpart but with the extra reach needed for complex setups. It features a patented deep-cradle design that holds the hose firmly in place without straps, and its flexible joints easily navigate around trees, campground posts, or landscaping. Despite its massive reach, it compresses down to a surprisingly manageable size for storage.

• Maximum reach: Full 20 feet of support
• Folded size: Compresses down to approximately 9 inches
• Structure: Reinforced joints to handle the extra length

Because of its length, this support requires more attention when expanding to ensure the slope remains uniform from end to end. On uneven ground, the middle sections can sometimes bow if the span is stretched to its absolute limit, so careful placement is key.

This is a must-have for drivers of large Class A motorhomes, long fifth wheels, or anyone who frequently camps at state parks where utility hookups are often far from the rig’s pad. It is overkill for small campervans or teardrop trailers that rarely use more than a 10-foot hose.

Metal Accordion Support – Valterra Slunky 20-Foot

For long-term setups or environments exposed to high winds and extreme temperatures, lightweight plastic supports can sometimes shift or degrade. A heavy-duty metal-reinforced support provides the structural heft required to keep a long sewer hose perfectly aligned. It anchors the hose against wind, ground movement, and the physical force of heavy dumping cycles.

The Valterra Slunky 20-Foot utilizes a metal frame combined with deep plastic cradles to deliver unmatched stability over a massive span. This hybrid design gives you the flexibility of an accordion-style support with the rugged weight of metal linkages that won’t blow away in a storm. The graduated height design ensures a natural, gravity-fed slope across the entire 20-foot run without manual adjustments.

• Frame material: Metal links with heavy-duty plastic cradles
• Length: 20 feet of continuous support
• Securing system: Included straps to lock the hose in place

This unit is significantly heavier than all-plastic supports, which means it adds to your overall cargo weight and requires a dedicated, dry storage space to prevent rust over time. Setting it up requires a bit more physical effort due to the resistance of the metal linkages.

This is the ultimate choice for full-timers who camp in windy, desert environments or areas with harsh winters where plastic-only models might fail. It is not recommended for weight-sensitive rigs or weekend travelers who prefer ultra-lightweight, quick-deploy gear.

Curved Camper Leveler – Andersen Hitches 3604

Achieving a proper sewer hose slope is impossible if the RV itself is not properly leveled. If your rig tilts away from the waste valves, water will pool inside your on-board plumbing lines before it even reaches the external hose. A reliable, precise tire-leveling system is the foundational first step for both interior comfort and proper exterior wastewater drainage.

The Andersen Hitches 3604 Curved Leveler offers an incredibly simple and precise way to level your trailer or motorhome. Instead of guessing with stackable blocks, you simply drive onto these curved ramps until your bubble level indicates you are perfect, then slide the included chocks underneath. They provide up to 4 inches of lift and are made from extremely durable, specialized polymers that won’t crack or slip on the ground.

• Lift range: 1/2 inch to 4 inches of precise leveling
• Weight limit: Up to 30,000 lbs
• Included in kit: One leveler and one locking chock

Note that curved levelers require a helper or a visible leveling system (like electronic levelers or a large bubble level mounted to the front of the trailer) to know when to stop driving. They also require sufficient clearance between tandem axles to fit properly.

This is a game-changer for towable RVers (travel trailers and fifth wheels) who want to level their rigs in under a minute without manual lifting. It is not designed for heavy Class A motorhomes that rely on built-in hydraulic leveling jacks.

How to Set Up and Maintain Your RV Sewer Supports

Setting up your sewer support should be one of the first things you do after leveling your rig and before pulling any waste valves. Begin by extending the support from your RV’s sewer outlet directly to the campground sewer connection, ensuring there are no sharp turns or kinks. Place your sewer hose into the cradles, working from the RV end down to the ground connection to guarantee a continuous, downward slope.

Once the hose is nested in the support, secure both ends using straps or weighted sewer caps to prevent the pressure of a dump from dislodging the line. Run a small amount of gray water first to test the flow and verify that the support does not sag, wobble, or tip over under the weight of liquid. If you notice any pooling or low spots, adjust the height of the individual sections or insert leveling blocks underneath to correct the slope.

Maintenance is straightforward but critical for sanitation and gear longevity. Always rinse your supports with clean water if they come into contact with wastewater, and let them dry completely before collapsing them for storage. Regularly inspect plastic hinges and metal linkages for wear, cracking, or rust, and store them in a dedicated utility bin separate from your fresh water hoses.

Key Factors When Choosing Support and Leveling Gear

The first factor to consider is the typical distance you expect to cover at your campsites. While a 15-foot support is the standard for most commercial RV parks, public parks or boondocking sites often require a 20-foot support to reach distant or awkwardly placed sewer inlets. Analyze your travel style to determine whether you need a highly flexible accordion model for curving around natural obstacles or a rigid channel system for long-term stationary parking.

Material choice impacts both the weight of your rig and how long the gear will survive the elements. All-plastic models are lightweight and completely rust-proof but can degrade under intense UV exposure or crack in freezing temperatures. Hybrid or metal-reinforced designs offer superior wind resistance and durability but require more storage space, add weight, and need routine cleaning to prevent corrosion.

Space is always at a premium in any alternative living setup. Look for gear that compresses down to a fraction of its extended size or nests together compactly to fit inside your utility bays. Ensure that the collapsed dimensions of your chosen support match the physical space available in your bumper storage or under-chassis storage tubes.

Conclusion

Managing your RV’s wastewater system doesn’t have to be a dreaded chore if you have the right gear supporting your setup. By investing in high-quality sewer hose supports and precise leveling tools, you protect your plumbing, satisfy campground regulations, and ensure a clean, stress-free utility connection. Keep your slope steady, secure your lines, and enjoy the peace of mind that comes with a perfectly dialed-in mobile home.
