Mammoth Overland TL Tall Boy Trailer Assessment

Mammoth Overland is scheduled to roll out the primary Genesis Version of their new Tall Boy overlanding trailer earlier than the tip of the 12 months. We bought an early preview, nonetheless, spending a few days with the prototype tenting off-grid excessive within the mountains close to its Woodinville, Wash., manufacturing unit.

The Mammoth Overland TL Tall Boy is a uniquely designed and constructed off-road camper trailer constructed proper alongside Vashon Plane’s Ranger airplane. The TL makes use of the identical aircraft-quality manufacturing tools, aluminum supplies, and a spotlight to element. It ought to end in a trailer that can serve its house owners for generations.

Right here’s what this new Tall Boy overland trailer has to supply households who love off-roading, tenting off-grid, and doing it in a high-quality camper trailer designed particularly for such functions.

Briefly: Mammoth Overland’s latest entry within the off-road trailer market comfortably sleeps 4, has a rest room, 6’3” headroom, and is rock-solid in design. But its aircraft-grade aluminum physique makes it gentle sufficient to be towed by most mid-size pickups and SUVs. 

Off-Highway Camper Trailers

Overlanding and backcountry tenting have attracted a number of curiosity from youthful households who love the outside and getting far-off from the each day hustle and bustle of city/metropolis life at any time when time permits. The everyday RV journey trailer isn’t designed for that sort of use, particularly when the pavement ends and the highway to that out-of-the-way vacation spot turns to gravel, sand, or grime. That’s why “overlanding,” or “off-road” trailers have turn into the campers of selection.

The draw back of the everyday overlanding/off-road trailer is they’re normally inbuilt both a model of a teardrop-style sleep-inside design, or as a cargo-style trailer arrange with a roof-top tent to allow them to be towed over difficult backroads.

Teardrops sleep two inside and sometimes have lower than 4 ft of headroom, whereas the roof-top sleeping quarters of cargo trailer designs put you 9 ft above the bottom. So, making an attempt to accommodate a household of 4 in both could be difficult, particularly in the case of having a rest room and a cushty sleeping area.

The bigger, tandem-axle off-road camper trailers have extra space and options, however can simply high $100K. 

Mammoth Overland Tall Boy Assessment

Mammoth Overland’s 2,900-pound 2025 TL (Tall Boy) overlanding tenting trailer stands 9 ft tall and comfortably sleeps 4. It’s a limited-production, all-aluminum overlanding trailer that actually raises the roof on these norms, as I came upon whereas tenting within the prototype.

Not solely is the TL “Genesis Version” ruggedly constructed to resist essentially the most difficult of backcountry roads and off-road Jeep trails, but it surely additionally has an inside ceiling top of 6’3”, comfortably sleeps 4 on its king mattress in entrance, and 6’2” lengthy twin bunks on the road aspect. It additionally has an inside lavatory with a bathe, which is a key function for any family-oriented off-road trailer.

The Tall Boy can also be one of many lightest and least costly of “camper-style” tandem-axle off-road trailers to hit the market with an MSRP of $72,000 absolutely accessorized. And none of right this moment’s off-road/overlanding-type campers are constructed utilizing aircraft-grade supplies, design, manufacturing, and high quality management. There’s a cause for the latter parts of the Tall Boy.

Plane Manufacturing Method

“My strategy to the event of our off-road trailers might be a little bit bit completely different than different off-road trailer producers,” says Scott Taylor, Mammoth Overland’s president, who additionally had an extended profession as a manufacturing supervisor of quite a few Boeing army and business plane packages. Scott can also be the President/COO of Vashon Plane, Mammoth’s dad or mum firm.

“We designed this trailer with an plane producer’s mindset: to make it actually sturdy, actually gentle, and elegantly purposeful with minimal shifting elements. Our objective was to construct a ‘generational’ off-road trailer; one which could possibly be handed right down to the following technology, and the following,” says the long-time pilot.

Sleep With a View

Throughout our tenting journey, we made good use of the indoor lavatory, in addition to the array of USB and 110V plug-ins. And, we liked the sturdy two-piece door — the steps drop down like an airplane — that was very safe. The opposite facet of the Tall Boy that my spouse and I each thought was nicely executed was the view the a number of oval-shaped roof home windows alongside the roof sides gave of the encircling space.

“Home windows have been an vital a part of the preliminary design. I wish to expertise being outdoors whereas flying my Vashon Ranger,” Scott defined previous to us leaving the manufacturing unit, towing the TL behind his four-door Jeep Wrangler. “The identical factor is how I really feel about overlanding: I wish to be outdoors experiencing nature. So let’s be outdoors once we’re inside, have the openness of not being enclosed and cooped up.”

As for sleeping lodging within the Tall Boy, the thick king-sized foam mattress up entrance could be very snug. Two large RV-style home windows on all sides permit an ideal view and are absolutely adjustable to open so far as wanted for air flow. They’re additionally fitted with bug screens and shades like a conventional tenting trailer.

Down beneath, on the road aspect, are two 24” W x 6’2” L bunks adjoining to the slender aisle and throughout from the toilet. The higher bunk could be shortly and simply deployed so it hinges down from the wall to show the decrease bunk into a snug sofa.

Outside Cooking

Exterior is the kitchen. It’s situated on the off-side rear and serves because the again wall of the pass-thru storage compartment. The aluminum unit swings out, locking in place to offer a secure cooking platform with a two-burner propane range, small sink, and handy 42-quart, 12V freezer/fridge. The sink is fairly small, and on the prototype mannequin, it drained out on our ft — the manufacturing fashions can have a unique sink drain setup. 

Along with the swing-out kitchen, the TL additionally has a nifty foot-wide, 3-foot-long drop-down aspect panel for a prep desk — or a serving desk. And, it opens to disclose a three-shelf pantry that may be accessed from inside or outdoors.

We used the desk to carry a transportable Kenyon SilKEN smokeless electrical 110V grill that plugged right into a receptacle contained in the physique opening. The TL has USB, 12V, and 110V plug-ins conveniently situated all through the trailer.

Storage Options

Within the roomy rear storage compartment is a 50-gallon recent water tank, sufficient to final a household of 4 for a number of days off-grid tenting. The storage compartment can carry a number of gear, which is nice as a result of storage inside could be very restricted until gear is laid on high of the beds or stuffed into the vertical shelf on the entryway.

Up high of the Genesis Version Tall Boy is the 23Zero 270-degree awning that spreads out to offer cowl from the kitchen and across the rear of the tenting trailer. Deploying it requires a ladder — or climbing up the square-tube ladder mounted on the entrance of the TL. You can too carry 500 kilos of substances secured to the roof rack of the Tall Boy.

Tall Boy Towing

On the highway and on the path, the Tall Boy tows simply as a result of it has about 400 kilos of tongue weight, which makes trailer-induced sway nonexistent — at the very least, that’s the way it towed behind Scott’s four-door Wrangler. The lengthy tongue, Lock ‘N’ Roll articulating hitch, and tandem Timbren Axle-Much less suspension helped isolate the Jeep from the trailer when the terrain bought a little bit twisty and tough.

The lengthy tongue, 400-pound tongue weight, and Lock ‘N’ Roll hitch serve the Mammoth Overland Tall Boy nicely. Twin spares are a pleasant contact, too.

2025 Mammoth Overland Tall Boy Assessment Wrapup

Total, the Tall Boy Genesis Version tenting trailer seems and looks like it could be match for younger, adventuresome households. The aircraft-style monocoque design of the physique is designed to resist the pains of being towed over tough terrain reminiscent of that discovered within the Pacific Northwest, and the inside offers four-season consolation and an ideal view of these forms of environment.

As Scott says, “I believe we put a brand new spin on overlanding trailers with the Tall Boy.
