#The Ultimate All-Season Trailer: Wooly is a Game-Changer for Winter Camping Enthusiasts

What’s the best all-season camper trailer you can think of… If you are not yet ready with a name, you should give the WLY or Wooly from Mammoth Overland more than just a cursory glance. The trailer is built from the ground up for adventures in sub-zero temperatures, with your house-like level of insulation, power backup to explore the wilderness for more than a day, and space enough to haul your snow sports equipment along.

Mammoth Overland WLY trailer is likely to retail for $56,900. Shipping will begin in the second quarter of 2025, but the stellar camper trailer will only be built to order. Of course, you cannot commit to a trailer by its mere looks or a few feature highlights. The article thus delves into the exciting features onboard the WLY that would, if not instantly, eventually get you enticed to pre-order it.

Designer: Mammoth Overland

The durable all-season, off-road camper trailer is made entirely from aluminum, and as the company notes, is a worthy successor to the “Tall Boy” and “Extinction Level Event” trailers. As a potent hauling camper designed for riding the snow, the WLY features bronze Method Race Wheels with a 3PMS rating for confident grip in snow.

On the inside, an 11,500-BTU/hour VarioHeat heater from Truma – that’s made to keep up to 600-square-foot space cozy in sub-zero temperatures at elevations as high as 8,694 feet – ensures the ideal temperature. This with wool insulation on all the walls allows the Wooly (that’s where the name is derived from) to keep warm and comfortable in temperatures as low as -20 Fahrenheit or -28 degrees Celsius.

With the off-roading ability and substantial prowess to negotiate snow trails with confidence, the Wooly can be your perfect partner for winter sports activities like skiing, snowboarding, or snowmobiling in remote locations, where you previously thought camping wouldn’t be an option. Wool is not only a choice because it is an excellent natural fiber insulator, even when it is wet, but Mammoth Overland points out that it’s hypoallergenic and fire resistant as well, and interestingly keeps the enclosed space cool when the weather outside is warmer to your liking. Coupled with an installed RTX 2000 air conditioner, this makes WLY all-ready for summer camping as well.

The trailer arrives with its water storage and supply, while four alternative energy options power its built-in 800-Amp-hour lithium battery.  The 21-gallon water tank is connected to a heater with pipes plumbed to ensure water does not freeze even when the mercury is dipping at an alarming rate. Stationed at the camp, the WLY allows you to prep a meal in the kitchen located in the annex that deploys over the rear hatch. A heated king-size mattress blesses you with a cozy sleep. A 23ZERO Bushman awning room makes extra space to keep you from carrying wet clothes into the cabin. When it’s a sunny day and you have the snow gear unloaded from the roof rack, climb up to the roof-based observation deck to bask in the sun or enjoy the expansive white panorama.
