Today’s RV (p)review is of the forthcoming Tall Boy trailer from Mammoth Overland. This is a new offering from the company that is much more travel trailer and less teardrop-style, but it retains the company’s focus on overlanding.
Mammoth Overland is actually owned by Vashon Aircraft in Woodinville, Washington. Interestingly, the last time I can think of an aircraft company that made travel trailers it was the Spartan Aircraft Company. Those trailers remain collectible some 70 years after they were built.
Like those vintage trailers, the ones built today by Mammoth Overland are all aluminum construction, but the intended market is vastly different.
“As a teen growing up in Montana, I explored on foot places that most people couldn’t. I always lamented that more families couldn’t experience these amazing, remote spots,” said Mammoth Overland President Scott Taylor. “We gave Tall Boy 22 inches of ground clearance, so that families could confidently and comfortably access parts of our country typically off limits to off-road trailers. Tall Boy combines the durability of our HV and ELE trailers with the amenities and spaciousness of home.”
What is the Mammoth Overland Tall Boy
Standing nine feet tall, Tall Boy features a king-size bed, two full-length bunk beds, and full bathroom. Tall Boy is designed to take families further and more comfortably into the back country.
Just like Mammoth Overland’s HV and ELE trailers before it, Tall Boy’s aircraft-grade all-aluminum construction started with the king-size mattress—the feature Taylor’s wife required. Designers then added two additional sleeping bunks, both long enough to comfortably sleep a six-foot-two-inch individual. When not in use for sleeping, the top bunk folds down to create a couch-like sitting area. The lower bunk also has access to a cubby in which an additional set of lighting controls are located. Beneath the king bed is storage space. Since designers created Tall Boy for families, the interior has dozens of USB ports throughout. And it includes a 24-inch LCD television.
Tall Boy’s bathroom is a standout in the segment—and one that the Mammoth Overland team agonized over for months, redesigning it several times before landing on the final concept. It brings all the luxuries of home into the backcountry, including a shower, sink, and cassette toilet. Both the shower and sink benefit from Tall Boy’s instant hot water system, which is fed by the onboard 50-gallon water tank.
Campers are kept warm by a propane-fired Dickenson heater. Should they require a bit of fresh air, Tall Boy’s windows tilt outward for additional airflow. Also, it features two reversible fans in its roof.
Foldout kitchen on the Mammoth Overland Tall Boy
Stepping outside through the aviation-style two-piece door (don’t forget that Mammoth Overland’s parent company is Vashon Aircraft), and down the fold-down stairs, campers can access the foldout kitchen. Both the kitchen and the stairs are covered by a 270-degree 23 Zero awning. Rather than move it inside, designers kept Tall Boy’s kitchen outside because, well, overlanding is an outdoor experience.
Tall Boy’s kitchen features a sink, stove, and 42-quart fridge. Though the kitchen is exterior, the pantry is a passthrough design, accessible from inside the cabin or outside.
Slightly more hospitable than the ELE trailer before it, Tall Boy is nonetheless off-road capable. It rides on dual independent axles to which 17-inch wheels wrapped in 33-inch tires are mounted. This setup gives Tall Boy a whopping 22 inches of ground clearance—far more than the next closest competitor. Tall Boy includes not one but two full-size spare wheels and tires, a front-mounted exterior molle panel, and ladder that provides access to the roof. The standard roof rack is rated to hold 1,000 pounds static and 500 pounds dynamic.
“Tall Boy is a testament to the incredibly skilled Mammoth Overland team,” Mammoth Overland President Scott Taylor added. “They have proven themselves to be extremely capable and maneuverable while taking hit after hit and never slowing down—just like Tall Boy. I am so proud of this trailer and the entire Mammoth Overland team.”
Electricity in the Mammoth Overland Tall Boy
Electricity comes from one Renogy 400-amp-hour smart lithium-ion-phosphate battery with self-heating technology. The batteries can be recharged while driving or by two 100-watt Renogy lightweight flexible solar panels, which rest atop the exterior 23 Zero awning.
Pricing for the fully loaded Mammoth Overland Tall Boy “Genesis Edition” trailer is priced at $72,000, and deliveries are scheduled to begin in Q4 2024. Like all Mammoth Overland trailers, Tall Boy is built to order. Pricing of standard Tall Boy trailers will be announced closer to the conclusion of the limited-run Genesis Edition.
Mammoth Overland is taking deposits now for Tall Boy’s limited production run. Deliveries will begin in the fourth quarter of 2024. Buyers can learn more about Tall Boy on the Mammoth Overland website.
Tall Boy will make its public debut at Overland Expo West in Flagstaff, Arizona, May 17-19, 2024, at the Mammoth Overland booth L26.

Despite the aluminum costruction, it looks very “beefy”. Is it really light enough to be towed up steep grades on unimproved roads/trails by Jeep Wrangler?
Not sure I’d want to spend that kind of money to cook outside…
Thank you, Tony! 🙂 My, my, my, that is some RV!?!?! The price is steep, but there is a lot for the money. It certainly appears capable of going almost anywhere. 🤔😯 Thanks again and safe travels! 🙂
I predict this will be a very limited production model. The high clearances (under and overhead) = high center of gravity, isn’t conducive to overland camping. The price point is way out of the ballpark for most overlanders.
They will sell a few units to the Trust Fund Overlander Wanabees, which will never get used, and will sit in storage until they become “collectable”.
Tony, what is the hitch weight of that trailer, and what is the Cargo Carrying Capacity (payload capacity) of the Jeep in the pic? I’m guessing that configuration puts the Jeep way over the CCC. To me, that pic is false advertising.
