HV — The Standard

Mammoth Overland HV off-road trailer with kitchen deployed at a campsite — 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 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)

Mammoth Overland WLY off-road trailer in snow with snowshoes leaning against the wheel — 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 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.

TL — Room for the Whole Family

Mammoth Overland TL off-road trailer towed by a Jeep Wrangler in a grass field — 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 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

Mammoth Overland SKL hard-sided rooftop tent open on a truck at sunset — The Mammoth Overland SKL, deployed and ready for the night — a hard-sided rooftop tent built with the same security-minded design as the rest of the lineup.
