Mammoth Overland builds six off-road trailer and camper models, each engineered using the same aerospace-grade aluminum monocoque construction shared with parent company Vashon Aircraft. From the lightweight standard HV to the fully-loaded XLE, every Mammoth Overland model is built to order in Woodinville, Washington, and shares the same core philosophy: aircraft-level engineering applied to off-road camping.

HV — The Standard

The Mammoth Overland HV, set up at camp with its rear kitchen deployed — the standard trailer that started the Mammoth lineup.

The HV is Mammoth Overland’s entry point: a 1,650-pound teardrop trailer built on the same monocoque aluminum platform as the rest of the lineup, starting at $32,500. It’s the lightest, most affordable way into the Mammoth ecosystem, and the foundation that the WLY and ELE are both built on top of.

WLY — Built for Extremes (in Both Directions)

The Mammoth Overland WLY — ‘Wooly’ — built to keep campers warm down to -20°F, photographed deep in snow country.”

The WLY shares its core cabin with the HV but adds dramatically upgraded insulation — R25 in the floor, R12 in the walls — keeping occupants comfortable down to -20°F. That same insulation works just as well in reverse, making the WLY a genuine four-season trailer rather than a single-purpose winter rig. Starting at $59,500.

ELE — Self-Sufficiency, Engineered

The Mammoth Overland ELE — ‘Extinction Level Event’ — built for self-sufficiency, security, and going completely off-grid.

The ELE built Mammoth Overland’s reputation for genuinely extreme engineering: a pressurized cabin with medical-grade air filtration, an integrated bear-spray defense system, weapons storage, and optional Level 3 ballistic protection. Starting at $67,000.

TL — Room for the Whole Family

The Mammoth Overland TL, ready for the trail — full-height family capability built on the brand’s signature aerospace-grade platform.

The TL (“Tall Boy”) trades the teardrop shape for a full-height, stand-up cabin with a king bed, two bunks, and an indoor bathroom with shower — built for families who want off-road capability without sacrificing livability. Starting at $72,000.

XLE — The Most Capable Trailer Mammoth Has Ever Built

The XLE, nicknamed “Xtinction-Level Escape,” combines the TL’s full-height family-friendly platform with the ELE’s hardcore survivalist systems — plus a few new ones, including bulletproof windows, 360° night-vision CCTV, and a 37-millimeter flare launcher. Starting at $123,994.

SKL — Security on the Roof

The SKL is Mammoth Overland’s hard-sided rooftop tent, combining the brand’s security-minded design language with a sleek, compact footprint. Production timeline and pricing to be announced.
