Hauling waste to the dump station gets old fast, and a good portable tank cuts that chore down to size. The right pick depends on whether you want a tow-behind cart for weekend trips, an installed holding tank for a build, or a small accessory that keeps the campsite tidy. This lineup sorts through five solid options, each aimed at a specific kind of camper, builder, or weekend traveler.

A Closer Look At Each Pick
The RecPro is the kind of cart that quietly solves the worst part of RV life: hauling a full black tank across a gravel lot to the sewer. With 36 gallons of working capacity, it covers a long weekend of moderate use without forcing a mid-trip dump run, and the no-flat tires mean it rolls over campground pavement without the slow leak that plagues cheaper caster wheels.
Built around a thick polypropylene body, it tolerates rough drops from a truck bed and shrugs off UV exposure through the summer. Unlike the fixed holding tanks further down this list, this one is a self-contained station, so the owner fills it, hitches the included tow handle, and walks it to the dump. Weekend families and full-timers running tight gray-water setups get the most out of it.
The Helpful Details
- 36-gallon working capacity covers multi-day trips for most couples
- No-flat solid tires handle gravel without flats or slow leaks
- Heavy-duty polypropylene resists drops and rough handling
- Tow handle makes solo trips to the dump station realistic
- Wheeled design stores upright against the RV when not in use
Things To Consider
- Large capacity means a heavy load when full, so plan the route downhill when possible
- Rinsing the interior thoroughly takes a hose and some patience after each dump
Key Product Details
Who It Suits Best
RV owners running 2 to 5 day stays at sites with limited sewer hookups who want one tow-and-dump unit instead of frequent drives.
Look Elsewhere When
Builders needing a permanent holding tank will find the Class A Customs 27 Gallon RV Waste Holding Tank a better fit for a fixed install.
The 14-gallon Class A Customs is a serious install-grade holding tank shrunk down for tight quarters. Tiny house builders and teardrop trailer owners pick it because it slips into a small floor cavity without eating the whole build, while still offering enough volume to skip the dump station on short trips.
Unlike the RecPro above, this is not a portable cart. It is a fixed tank meant for a plumbed setup, so the owner decides where the inlet and vent land and brings in a certified tech for the install. Medium-density polyethylene (MDPE, a tough, mid-weight plastic used widely in fluid tanks) gives the seamless one-piece body a long working life, and the 3-inch ABS female outlet feeds straight into a standard drain plumbing run.
Standout Benefits
- 14-gallon footprint fits under benches or in narrow trailer floors
- Seamless one-piece MDPE construction resists cracking at weld lines
- 3-inch ABS outlet accepts standard RV drain plumbing
- Made in the USA with consistent resin quality
Worth Noting
- Inlet, vent fittings, dump valve, and piping all sold separately, so budget for extras
- Outlet position is fixed and cannot be moved once shipped
- Requires a certified installer if the owner lacks plumbing experience
- Not rated for fresh or potable water, so it must stay on the waste side of any plumbing map
Made For
Tiny home and small camper builders who want a compact, plumbed-in waste tank and are comfortable sourcing fittings separately.
Skip It When
Anyone who just needs a towable cart should pick the RecPro 36 Gallon RV Portable Waste Tank instead, since no install is required.
The 27-gallon WT-2700 sits in the sweet spot for a serious van or small motorhome build where space is tight but capacity still matters. Stepping up from the 14-gallon unit above more than doubles the working volume, which buys a real weekend of gray-water use before anyone touches a dump valve.
Same MDPE resin, same one-piece seamless build, same 3-inch ABS outlet, just in a larger box. The trade-off shows up in floor space: this tank needs a planned cavity, and the inlet plus vent still have to be drilled and plumbed by the owner. Custom van converters, skoolies, and serious trailer rebuilds get the most out of it.
Practical Advantages
- 27-gallon capacity handles a full weekend for two campers
- MDPE one-piece body avoids seam failure under road vibration
- Standard 3-inch ABS outlet drops into common RV drain plumbing
- Larger footprint still fits under most RV benches and platforms
Points To Note
- Heavier empty weight than smaller Class A Customs tanks, so reinforce the mounting surface
- No inlet, vent, dump valve, or piping in the box, so plan a separate parts order
- Over-tightening fittings can crack the outlet, so use caution during install
Quick Facts
Whose Shelf It Belongs On
Van life builders and skoolie converters who want one install-grade tank big enough to skip daily dumping on weekend trips.
Consider Something Else When
Anyone needing a cart-style, tow-to-the-dump unit will prefer the RecPro 36 Gallon RV Portable Waste Tank.
The WT-2400 lands between the 14-gallon and 27-gallon Class A Customs tanks, which makes it the friendliest middle ground for a standard teardrop or small trailer build. 24 gallons is enough for a couple of days of moderate use without forcing the owner into a permanent upgrade.
The build story matches its siblings: one-piece MDPE shell, 3-inch ABS outlet, no fittings in the box. Weekend trailer builders usually pair this tank with a basic vent, gate valve, and PVC run for a clean, low-cost install. The trade-off is the same as the other Class A Customs models, since you handle the inlet and vent placement yourself.
What Stands Out
- 24-gallon middle capacity suits most small trailers
- Seamless MDPE body avoids leak-prone welded seams
- Standard 3-inch ABS outlet fits common drain plumbing
- Made in the USA for consistent resin quality
- Lighter empty weight than the 27-gallon sibling, easier to lift into place
Trade Offs
- No inlet, vent, or valve hardware included, so budget for a separate parts kit
- Outlet cannot be relocated after delivery
- Requires venting during use to prevent pressure build-up
Best Suited To
Teardrop and small travel trailer builders who want a mid-size, install-grade waste tank without stepping up to the heaviest option.
A Better Fit Elsewhere
Couples needing a towable solution for longer stays will find the RecPro 36 Gallon RV Portable Waste Tank a more practical match.
The Memorywuu is not a holding tank, and pretending otherwise would not help anyone. It rounds out this lineup because RV and tent campers who manage their own waste still need somewhere clean to toss trash between dump runs, and a folding bin with a zippered lid keeps the campsite tidy without eating cabinet space.
The cotton-linen body with a PE waterproof layer handles damp food scraps and wet wipes better than a paper grocery bag. The zippered lid is the real upgrade over cheap pop-up bins, since it stops raccoons, flies, and wind from scattering garbage overnight. For travelers short on storage, it folds flat into a drawer.
What Makes Sense
- Cotton-linen plus PE waterproof layer handles damp waste without leaking
- Zippered lid keeps scavengers and wind out
- Folds flat for under-bed or under-seat storage
Small Caveats
- Soft-sided body needs a frame or stand to stay open during use
- Not a substitute for a true waste tank, only handles dry trash and sealed scraps
The Right Fit
Tent campers and RV travelers short on cabinet space who want a clean, foldable trash bin for the campsite.
Reach For A Different Pick When
Anyone needing an actual black-water holding tank should look at the Class A Customs 24 Gallon RV Waste Holding Tank for a mid-size install option.
What To Weigh Before Choosing A Portable Waste Setup
Matching capacity to trip length is the fastest way to avoid frustration. A 14-gallon tank covers a short weekend for one or two people who watch their water use, while a 36-gallon tow cart buys real breathing room for families or longer dry-camp stays. Owners who run tall rigs with full kitchens usually find anything under 20 gallons runs out by day three.
Portability versus install is the other big fork. A wheeled tank like the RecPro rolls to the dump station with no plumbing work, which suits owners who do not want to open up a wall. Fixed MDPE tanks from Class A Customs need a planned cavity, fittings bought separately, and usually a tech on hand, but they vanish into the build and serve the plumbing on demand.
Material choice matters more than people expect. MDPE is a mid-weight plastic that resists road vibration and impact better than bargain polyethylene, and seamless one-piece bodies remove the weld-line leak paths that show up in cheaper welded tanks. Owners running rough forest roads benefit most from that extra toughness.
Finally, think about the small accessories early. Fittings, vent hardware, gate valves, and piping are typically sold separately for install-grade tanks, so the total project is more than the tank itself. Budgeting for those extras up front prevents a stalled build halfway through the weekend.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
A common trap is buying a tank by capacity alone and ignoring the footprint. A 36-gallon tank that does not fit the planned bay is useless, and a 14-gallon tank that fits but empties daily gets old fast. Measure the cavity first, then match the tank.
Another misstep is assuming fittings come in the box. Install-grade Class A Customs tanks ship with just the outlet, so the inlet, vent, valve, and piping all need separate orders. Shoppers who skip this step end up with a useless hunk of plastic until the parts arrive.
What Separates Premium From Basic
In this category, premium usually means seamless MDPE construction, fixed but standard 3-inch ABS outlets, and tanks built to survive road vibration over years. The basic tier leans on thinner polyethylene and welded seams that hold up fine for a season or two, then start to creep. The upgrade pays off for anyone running long trips or rough roads, while casual weekend campers may not notice the difference.
