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.Which Mammoth Overland Model Is Right for You?
|
|---|
HV — The Standard
The HV is Mammoth Overland’s entry point: a 1,650-pound teardrop trailer with Timbren 3500HD axle-less independent suspension, starting at $32,500. It’s the lightest, most affordable way into the Mammoth ecosystem, and the foundation the WLY and ELE are both built on.
WLY — Built for Extremes (in Both Directions)
The WLY shares its core cabin with the HV but adds dramatically upgraded insulation — R25 in the floor and wool-lined R12 walls — plus a Truma VarioHeat furnace, winter-proofed heated water lines, and an 800Ah self-heating lithium battery bank. That same insulation works in reverse, making the WLY a genuine four-season trailer. Priced at $59,500.
ELE — Self-Sufficiency, Engineered
The ELE built Mammoth Overland’s reputation for genuinely extreme engineering: a sealed pressurized cabin with E.L. Foust air purification, an integrated bear-spray defense system, weapons storage, and bulletproof windows standard. Level 3 ballistic protection is available. Starting at $69,500.
TL — Room for the Whole Family
The TL (“Tall Boy”) trades the teardrop shape for a full-height cabin with 6’3″ of headroom, a king bed, two full-length bunks, and an indoor shower and sink — built for families who want off-road capability without sacrificing livability. Starting at $69,500.
XLE — The Most Capable Trailer Mammoth Has Ever Built

The XLE, “Xtinction Level Escape,” combines the TL’s full-height platform with the ELE’s survivalist systems — plus new ones, including 1″ bulletproof windows throughout, 360° night-vision CCTV, remote-activated sonic defense, and a 1,200Ah battery bank. A 37-millimeter smoke and flare launcher is available as an option. 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. SKL is available now, starting at $11,500.
