8 Ways to Secure a Portable Gray Water Tote to an RV Ladder for Boondocking

Boondocking in remote public lands offers unparalleled freedom, but it also presents the logistical challenge of managing waste water without hookups. A portable gray water tote is an essential off-grid tool, yet finding a safe space to store this bulky, dirty container during transit can easily clutter your interior or storage bays. Securing the empty tote to your RV’s exterior ladder is the ultimate space-saving solution, provided you use the right gear to keep it locked down tight against highway-speed winds and bumpy dirt roads.

Crucial Safety Factors for Mounting Heavy Tote Tanks

RV ladders are not indestructible structures; they have strict weight limits, typically ranging between 200 and 250 pounds. While a portable gray water tote is relatively light when empty (usually between 10 to 30 pounds), it becomes immensely heavy and dangerous if filled with water. Never transport a full or partially filled gray water tote on your RV ladder, as a 28-gallon tote filled with water weighs over 230 pounds, which can instantly tear the ladder mounts right out of your RV’s thin fiberglass walls.

Beyond static weight limits, dynamic forces—such as wind resistance, highway vibrations, and sudden bumps—multiply the stress placed on your mounting system. A tote acts like a sail on the back of your rig, catching turbulent air currents that want to twist and pull it away from the ladder frame. For this reason, your mounting configuration must eliminate all independent movement, ensuring the tote behaves as an integrated extension of the vehicle rather than a loose, bouncing projectile.

Ratchet Strap – Rhino USA Heavy Duty Ratchet Straps

A primary restraint tool must eliminate all potential shifting under high wind loads, and a high-quality ratchet strap does exactly that. By utilizing mechanical leverage, these straps pull the tote tight against the ladder frame, eliminating the elastic bounce that lesser straps allow. This mechanical lockdown ensures that even on washboard dirt roads, your tote remains completely motionless.

The Rhino USA Heavy Duty Ratchet Straps offer a massive break strength and feature padded handles that will not tear up your hands during tensioning. The spring-loaded retention clips on the S-hooks ensure the straps stay anchored to the ladder rungs even before you apply tension, solving a major frustration of solo rigging. The high-visibility, heavy-duty webbing is designed to withstand abrasive plastic edges and harsh outdoor exposure.

• Break strength: 5,208 lbs (Working Load Limit: 1,736 lbs)
• Strap width: 1.6 inches for wide weight distribution
• Anodized ratchets with padded ergonomic handles
• Safety clip-equipped full bend S-hooks

Ratchet straps have a slight learning curve, particularly when releasing tension on a tightly wound spool. Over-tightening can easily crush the plastic shell of your gray water tote or bend your aluminum ladder rungs if you crank them down with too much leverage. It is critical to tighten them until snug and firm, rather than forcing the ratchet past its natural resistance.

This is the ultimate choice for RVers carrying larger 28- to 36-gallon totes on long highway stretches where high-speed crosswinds are expected. It is overkill for tiny, lightweight 10-gallon totes where simple lashing straps can suffice without the risk of crushing the plastic.

Ladder Carrier – Stromberg Carlson LA-102 Universal

A ladder carrier acts as a physical shelf to hold the vertical weight of the tote, allowing your straps to focus purely on pulling the tank inward. Without a shelf, gravity constantly pulls the tote downward, forcing your straps to work twice as hard to prevent sliding. Utilizing a dedicated carrier transfers the weight directly to the ladder’s structural rungs.

The Stromberg Carlson LA-102 Universal chair/carrier rack hooks directly over your ladder rungs to create a sturdy, physical cradle. It is constructed from lightweight, rust-proof aluminum that matches the aesthetic of standard RV ladders while providing a stable, dual-pronged support system. The powder-coated finish prevents metal-on-metal rubbing, reducing the risk of wear on your ladder’s structural tubing.

• Weight capacity: Up to 50 lbs of cargo
• Material: High-strength, lightweight rust-resistant aluminum
• Secures with a simple, tool-free pin system
• Prongs fold flat when not in use to save rear-end clearance

While this carrier provides the physical shelf, it does not secure the tote by itself; you must still use straps or locks to bind the tote to the frame. Additionally, check the spacing of your ladder rungs, as this carrier relies on standard rung intervals to seat properly and fold away cleanly.

This is perfect for boondockers who want a permanent, easy-to-use structural base that takes the physical strain off their arms during mounting. It is not suitable for RVs with non-standard, custom-spaced, or curved ladder designs where the hooks cannot sit level.

Cam Buckle Strap – Lashing Straps by SmartStraps

For mid-sized totes, a cam buckle strap offers a quick, highly reliable securement method that completely avoids the risk of crushing plastic. Unlike ratchets, cam buckles rely on manual pull strength to tighten, making it nearly impossible to over-tension and damage your gear. They are incredibly fast to thread and release, saving time during setup and breakdown.

The Lashing Straps by SmartStraps utilize a simple thumb-press cam buckle mechanism that allows you to pull the strap tight using only your physical strength. These straps feature high-visibility green webbing and a protective pad behind the metal buckle to prevent scratches on your tote or ladder finish. The ribbed buckle teeth grip the polyester webbing firmly, preventing slippage even under vibration.

• Working load limit: 300 lbs (900 lbs break strength)
• Strap length: 10 feet for easy single-loop wrapping
• Steel cam buckle with non-marring protective backing pad
• Weather-resistant, high-tenacity polyester webbing

Because tension is applied purely by pulling the loose end, these straps are limited by your arm strength and can loosen slightly if the webbing becomes soaked in a heavy downpour. It is wise to tie a simple half-hitch knot right behind the buckle with the excess strap tail to prevent any potential slippage during long highway hauls.

This product is ideal for owners of smaller 12- to 21-gallon gray water totes who want a fast, daily-use rigging solution without the complexity of ratchets. It is not recommended as the primary restraint for massive, wind-catching 36-gallon totes on high-speed interstate routes.

Bungee Cord – Keeper Heavy-Duty Bungee Cord

Bungee cords serve as excellent tension-management accessories, keeping loose components from rattling or shifting on the road. They are not meant to bear structural loads, but rather to pull slack out of your mounting setup and dampen minor vibrations. Utilizing them alongside rigid straps ensures a completely silent transit experience.

The Keeper Heavy-Duty Bungee Cord features a premium outer jacket that resists UV degradation and rot under harsh desert sun conditions. Its spring-steel hooks are coated in a tough, non-marring vinyl layer that prevents scratches on your ladder, and the inner rubber core retains its elasticity far longer than cheap, generic convenience-store bungees.

• Inner core: Premium continuous-strand virgin rubber
• Outer sheath: UV-resistant, woven polyester jacket
• Heavy-duty vinyl-coated steel hooks to prevent scratching
• Available in various lengths for custom-tension setups

Bungee cords should never be used as the primary method to secure a heavy gray water tote to an RV ladder. They stretch under load, meaning high winds or sudden bumps will cause the tote to bounce, potentially fatigue-testing your ladder welds or snapping the cords.

This is an excellent secondary accessory to wrap around the wheels or handle of your tote to stop annoying rattles and squeaks while driving. Do not buy this if you expect a single elastic cord to safely hold a bulky plastic tank to your bumper at highway speeds.

Cable Lock – Master Lock Python Adjustable Cable Lock

Security is a major concern when mounting valuable gear to the exterior of an RV. A cable lock plays a dual role: it provides a robust mechanical backup to your primary straps and deters opportunistic theft when your rig is left unattended. This ensures your tote remains on your ladder both during travel and while parked at remote trailheads.

The Master Lock Python Adjustable Cable Lock is uniquely suited for this task because the braided steel cable can be pulled tight through the locking mechanism to any exact length. Unlike traditional cable locks that leave slack to bounce around, the Python locks at your desired tension, gripping the tote handle and ladder rungs simultaneously. The weather-resistant vinyl coating protects your equipment from scratches, while the rust-resistant locking body holds up to mud, rain, and road salt.

• Cable diameter: 5/16-inch (8mm) braided steel
• Fully adjustable length from 6 inches to 6 feet
• Scratch-resistant vinyl sleeve and rust-resistant lock body
• Patented locking mechanism holds cable tight at any position

The locking mechanism can become stiff if exposed to constant road grit and dust kicked up by your RV’s rear tires. Applying a quick squirt of dry graphite lubricant into the keyway once a season will keep the tumblers spinning smoothly.

This is a must-have piece of gear for boondockers who leave their rigs unattended at trailheads or dispersed campsites and want to deter thieves. It is not a replacement for heavy-duty load-bearing straps, but rather the ultimate secondary safety and security device.

Heavy-Duty Gear Tie – Nite Ize Original Gear Tie

When mounting a tote, small parts like tow bars, wheels, and hose caps love to rattle, spin, and flap in the wind. A heavy-duty gear tie is the perfect tool to organize and freeze these loose components in place. It acts as a reusable, non-destructive twist tie that installs in seconds without tools.

The Nite Ize Original Gear Tie is a massive, heavy-duty twist tie with a tough, grippy rubber exterior and a strong, bendable wire interior. It holds its shape perfectly under pressure, is completely waterproof, and won’t rust or scratch your ladder’s aluminum finish. You can wrap and twist it in seconds without struggling with knots, buckles, or mechanical hardware.

• Length: 32 inches or 64 inches for versatile wrapping options
• Internal wire: Tough, bendable high-grade steel
• Exterior: UV-resistant, grippy vulcanized rubber sheath
• Reusable thousands of times without losing holding power

While incredibly strong for their size, gear ties are not designed to carry structural load or resist high highway wind forces on their own. They are best used to bundle the tote’s tow bracket, secure loose discharge caps, or pin down the spinning wheels of the tote.

This is the perfect companion tool for organized RVers who hate dangling straps, rattling wheels, or loose tow bars. It is not suitable for anyone looking for a primary, load-bearing mounting system to anchor a 30-pound plastic tank to a wall.

Cargo Net – PowerTye Heavy-Duty Cargo Netting

A cargo net is designed to envelope the entire body of the tote, distributing holding pressure evenly across its surface. This prevents wind from getting underneath the plastic shell and lifting it, while also catching any loose items that might detach during transit. It acts as a comprehensive “catch-all” safety net.

The PowerTye Heavy-Duty Cargo Netting is designed with tight 2-inch by 2-inch mesh squares to ensure nothing slips through, including small hose attachments or structural lips on your tote. The net uses heavy-duty, adjustable ABS plastic hooks that won’t scratch your ladder rungs but can be repositioned to customize the tension. This net distributes the wind load across the entire surface of the gray water tote, preventing localized stress points.

• Net size: 15 inches by 15 inches (stretches up to 30 inches)
• Grid size: Tight 2-inch by 2-inch mesh squares
• Hooks: Six adjustable, non-scratching ABS plastic hooks
• Cord thickness: 4.4mm heavy-duty latex rubber core

Over-stretching the net beyond its designed limits will prematurely wear out the elastic core, causing it to sag over time. Ensure you choose a size that fits snugly over your tote without requiring maximum stretch just to hook onto the ladder rails.

This is ideal for RVers who want a comprehensive, “catch-all” secondary layer of safety over their tote, especially those carrying oddly shaped tanks with integrated hose storage. It should not be used as a standalone mounting system without rigid straps underneath it.

Mounting Bracket – Camco Rhino Tote Tank Ladder Holder

For those who want an engineered, direct-fit solution, a dedicated mounting bracket removes all the guesswork from DIY rigging. It is designed to physically mount to the ladder rungs and cradle the specific shape of a gray water tote. This specialized design ensures maximum security with minimal setup time.

The Camco Rhino Tote Tank Ladder Holder is engineered specifically for this exact task, removing all the guesswork from DIY rigging. It is constructed from heavy-duty, powder-coated steel and hooks securely over two ladder rungs, creating a stable saddle that cradles your tote’s handle. It includes a built-in nylon strap to pin the tank flat against the ladder frame, preventing bouncing or shifting during travel.

• Material: Heavy-duty powder-coated steel and aluminum
• Fits most standard RV ladders and Rhino/tote tank brands
• Includes an integrated holding strap with buckle
• Weighs under 5 pounds while adding minimal depth to your rig

This holder is designed primarily around the dimensions of Camco Rhino tote tanks, though it fits many other popular brands. Always double-check your ladder’s rung-to-rung spacing and the design of your tote’s integrated handle to ensure a clean, drop-in fit.

This is the best choice for travelers who want a dedicated, professional-grade solution that looks neat and mounts in seconds. It is not ideal for those on a tight budget who prefer a universal DIY approach using standard straps and carriers.

How to Properly Balance Your Gray Water Tote on the Ladder

Proper weight distribution is essential when mounting a bulky item like a gray water tote to your RV’s ladder. Always aim to place the center of gravity of the tote as low on the ladder as possible, ideally keeping the bottom of the tank supported by the bumper or a dedicated lower bracket. This low positioning reduces the leverage force exerted on the top ladder mounts when your RV sways or turns corners.

Center the tote horizontally on the ladder rungs so that wind resistance is distributed equally across both vertical rails of the ladder frame. If the tote sits off-center, wind drag will push unevenly against one side, twisting the ladder mounting brackets and loosening the screws over time. Always secure the wheels of the tote facing inward or locked down, preventing them from catching the wind and generating aerodynamic lift.

Effective Ways to Prevent Tote Theft While Boondocking

Dispersed boondocking sites are often remote, making unattended gear left on the exterior of an RV an attractive target for opportunistic thieves. A high-quality gray water tote is a significant financial investment, and losing it can instantly ruin a dry camping trip. The most effective defense is a multi-layered security approach that combines physical visual deterrents with heavy-duty mechanical locks.

Threading a hardened steel cable lock through both the structural handle of the tote and the main vertical frame of your RV ladder is an excellent primary deterrent. Additionally, you can position the tote so that its wheels are blocked or strapped tightly, making a quick “grab-and-go” theft extremely noisy and time-consuming. For long-term storage or when leaving your rig for multi-day hikes, consider wrapping a bright, heavy-duty padlock chain around the center of the tank to signal to thieves that this gear is not worth the effort to steal.

How to Inspect Your Mounting System Before Every Drive

Before hitting the asphalt or navigating washboard dirt roads, a thorough pre-trip inspection of your mounting system is mandatory. Begin by physically grabbing the mounted tote and giving it a firm shake to check for any play or shifting. If the tote moves independently of the ladder, your straps have stretched or loosened and must be retensioned immediately.

Inspect all webbing straps for signs of UV degradation, fraying, or dry rot, paying close attention to the points where the straps bend around sharp plastic corners of the tote. Examine your RV ladder’s mounting points on the rear wall of your coach to ensure no screws are backing out or caulking has cracked under the stress. Spending two minutes on this checklist before turning the key can prevent a catastrophic highway accident and save you from losing a valuable piece of gear.

Conclusion

Securing your gray water tote to your RV ladder is a practical, space-saving strategy that keeps messy off-grid gear exactly where it belongs—outside your living space. By investing in high-quality straps, robust mounting brackets, and a reliable locking system, you can travel with confidence knowing your gear is safe, secure, and ready for your next boondocking adventure. Drive safely, double-check your rig, and enjoy the peace of mind that comes with a perfectly secured setup.
