The Mammoth HV is the teardrop trailer that started Mammoth’s journey, engineered for adventurers who want a lightweight, capable, and comfortable off-road camper for weekend getaways or extended backcountry journeys. Built with durability and practical comforts from the ground up, the HV packs a surprising amount of gear and amenities into its compact build.

 Compact Yet Capable Design
Designed for remote trails and rugged terrain, the HV uses tough Timbren 3500HD independent suspension and 30″ BFGoodrich KO2 all-terrain tires to go where your tow vehicle can go. Its lightweight design makes it easy to tow with most SUVs and trucks while keeping rugged off-road capability.

 Fully Equipped Outdoor Kitchen
The rear galley kitchen includes a 2-burner stove, sink, and electric cooler/fridge — perfect for cooking backcountry meals under the stars.

 Off-Grid Power & Essentials
Standard electrical and power features include a 100 Ah AGM battery, a 1 kW true sine wave inverter/battery charger, solar power hookup, and LED lighting throughout.

 Water & Comfort Amenities
The HV comes with a 21 gal water tank, on-demand hot water, and an outdoor shower setup with privacy shelter. A comfortable king-size mattress lets you rest comfortably after trail days.

 Practical Add-Ons & Utility
Additional features include rugged rock sliders, stabilizing jacks, LED rock lights, modular roof rack with cross rails, a large front storage box, a 2″ rear hitch receiver, and a portable cassette toilet.

 Expandable & Customizable
Upgrade your HV with optional accessories like an off-road hitch, a spare tire swing-out, rock guards , solar panel packages, cabin heater options, rooftop tents, and more so you can tailor the trailer to your adventures.

The Mammoth SKL (pronounced “Skull”) takes everything Mammoth Overland is known for — rugged construction, smart design, and overland capability — and distills it into an innovative hard-sided rooftop camper. Perfect for adventurers who want shelter above the ground and serious durability without hauling a full trailer, the SKL delivers a comfortable micro-camping cabin that’s ready to go wherever your rig can take you.

Rooftop Shelter Reinvented
Engineered with an all-aluminum monocoque structure — similar to aircraft construction — and insulated to R5, the SKL stands far above traditional fabric rooftop tents in strength and weather performance. It sets up in about 30 seconds with a fold-up front door design that makes deployment quick and easy.

Comfort for Two
Featuring dimensions of approximately 89″ long and 59″ wide, the SKL fits a king-length mattress with enough interior width between a queen and a full. That means two adults can sleep comfortably under the stars with a secure shelter overhead.

Power & Lighting
Standard power comes from an integrated 6 Ah Renogy battery that runs interior LED lighting and a three-speed bi-directional electric fan to help circulate air. For longer trips, you can upgrade to larger battery options (104 Ah or 208 Ah), and the unit is pre-wired for solar panels to extend your off-grid stays.

Windows & Ventilation
Six iconic porthole windows bring natural light and connection to the outdoors, while the roof-mounted fan keeps fresh air flowing — all while offering far better insulation and durability than canvas equivalents.

Optional Gear & Storage
Add an optional roof rack that’s rated up to 500 lbs static load to carry gear like bikes, rooftop storage boxes, or solar panels. This transforms your SKL into a multifunctional adventure platform right on your vehicle’s roof.

Easy Integration
Weighing about 300 lbs in its base configuration, the SKL is engineered to mount securely to most roof racks designed for rooftop shelters — bringing Mammoth’s rugged build quality to vehicles without the footprint of a trailer.

A rugged, cold-weather–optimized teardrop camper built to handle long winter nights and extreme temperatures while still delivering overland capability and comfort. Known as the “Wooly,” this trailer combines the proven Mammoth HV platform with enhanced insulation and heating systems for four-season exploration.

Designed for adventurers who refuse to let winter stop them, the Mammoth WLY lets you explore snowy peaks, frozen lakes, and remote backcountry with confidence. Featuring thick wool insulation, powerful heating, and overlanding-ready gear.

Four-Season Thermal Performance
The WLY features significantly enhanced insulation—R25 in the floor and R10 in the walls and ceiling—far exceeding typical trailer standards. The interior cabin is lined with wool for cozy warmth and comfort, even in sub-zero conditions. Heated water lines and tanks keep plumbing flowing when temperatures drop.

Powerful Heating & Climate Control
At its heart is a high-output Truma VarioHeat 11,500 BTU forced-air heater, capable of maintaining comfortable interior temperatures in extreme cold, bringing true winter camping capability to a compact trailer. A Dometic RTX 2000 air conditioner also helps keep the cabin cool in warmer months.

Fully Equipped & Rugged
In addition to its winter-ready upgrades, the WLY includes all standard HV features such as a 2-burner outdoor galley kitchen, electric cooler/fridge, 21 gallon water tank with heated plumbing, king-size mattress, LED lighting, and solar power hookup.

Off-Grid Power & Gear Storage
Power comes from multiple sources: shore power, towing vehicle power, dual 100 W solar panels, and an onboard WEN 4,000 W generator feeding an 800 Ah lithium battery bank, giving you sustained off-grid capability. The roof rack and observation deck carry recovery boards, Rotopax storage, a krazy beaver shovel and room for more.

Rugged Off-Road Capability
Built on Mammoth’s robust HV chassis with Timbren 3500HD independent suspension and 33″ all-terrain tires on bronze wheels, the WLY is ready for harsh trails. Recovery ready frame and durable exterior make winter routes more accessible.

Winter & Summer Ready
Though optimized for cold weather, WLY’s advanced insulation and climate control make it comfortable year-round, keeping interiors warm in snow and cool in heat. This trailer is as versatile as it is capable.
