Mammoth Overland’s “Wooly” Travel Trailer is a Beast Built for Winter

The mad scientists over at Mammoth Overland are back at it again. The company that brought us burly off-road towables like the ELE (Extinction Level Event) and the TL (Tall Boy) are up to their old tricks. The latest addition to the brand’s lineup is the all-new WLY Mammoth (pronounced “wooly”), a travel trailer built to take on the worst that Mother Nature can throw at it. That includes keeping owners warm in temperatures as low as -20ºF/-28ºC.

The secret to keeping the WLY Mammoth warm and cozy is using residential-like levels of insulation and an efficient 11,500 BTU heater. In this case, the furnace is a Truma VarioHeat that can keep a 600-square-foot cabin toasty and is built to continue to function at an altitude over 8,600 feet (2,621 meters)—something that comes in handy in the company’s home state of Washington.

“Winters in the Pacific Northwest are beautiful and majestic, especially in the mountains. I wanted to create a trailer that allows folks the ability to explore during winter for more than just the day,” Mammoth Overland President Scott Taylor said in a press release announcing the new RV. “With Wooly, our engineers exceeded my wildest dreams. During testing, we were able to maintain 85 degrees inside the trailer, even with the kitchen and both doors wide open, with a 27-degree outside temperature. WLY is a dream come true for four-season campers.”

If you know anything about insulation, you probably also know that the material’s “R-value” is an indication of how resistant it is to heat flow. In other words, the higher the R-value, the better the insulation is at keeping warmth trapped inside. For reference, most RVs have an R-value that ranges between R0 and R5. But according to Mammoth, the Wooly’s walls and ceilings have an R12 rating, while its floor is an impressive R25.

That alone will keep the interior comfortable, trapping both warm and cool air inside. But to further regulate the off-road trailer’s temperature, Mammoth added a Dometic RTX 2000 to the rig. This super-efficient A/C unit provides cooling functionality and can maintain a consistent temperature between 41ºF and 126ºF (5ºC – 52ºC).

Of course, you do need power to keep the WLY Mammoth’s Truma furnace running, but fortunately Mammoth has you covered there, too. The rig can be plugged into shore power, of course, but its onboard 800Ah lithium battery pack can also be charged via the tow vehicle’s alternator and dual 100W solar panels on the roof. Should the battery run out of juice, a 4,000W WEN generator serves as a backup.

Like most of Mammoth Overland’s other offerings, the Wooly’s kitchen is located outside. That may seem a little counterintuitive for an RV designed for use in cold conditions, but a pass-through window makes it easy to access from within the cabin. The galley does come equipped with a two-burner stove, a sink, and an electric cooler, which is all you need for whipping up meals after a day on the slopes or snowshoeing a trail.

Inside, the Wooly boasts a king-size bed, LED cabin lighting, and a generous amount of onboard storage. The rig also includes a portable cassette toilet, an outdoor shower, and a 21-gallon freshwater tank. 33” Toyo all-terrain tires, a 2” lifted suspension, front armor, an off-road Lock N Roll hitch, and electric brakes further bolster its already impressive off-road cred. Built-in ski and snowboard mounts, not to mention four exterior MOLLE panels, make hauling all of your gear a breeze.

The Mammoth Overland WLY Mammoth is available now with a starting price of $56,900. Considering its impressive list of features and cold-weather capabilities, that feels like a very reasonable price for a rugged off-road travel trailer. To find out more, visit the company’s website.
