Boulder camping trailer dedicated for EVs
American manufacturer of campers Colorado Teardrops has developed the Boulder, a camper trailer adapted for electric vehicles. Its teardrop form helps for low drag, and its lightweight is also key.
Nothing saps an EV’s range quite like towing. Usually, it has a big effect on the range, massively increasing drag while adding extra mass. A combination that can easily halve the supposed range of an EV.
That’s where Boulder is coming in, named after the hometown of its builder, Colorado Teardrops. The Boulder’s shape has been developed to limit the wind resistance and be as low-drag as possible.
Light and aerodynamic
The aerodynamic trailer is also built of lightweight materials so that the total weight is down to 885 kg. And most of that weight is due to the battery pack Boulder has built into its frame. This 75 kWh lithium-ion battery is supposed to recharge your car at a destination where charging infrastructure is still unheard of.
“The ability to return an electric vehicle to its original range and provide recharging capabilities through renewables will extend camping opportunities far beyond the current range and enable a new level of environmentally responsible camping possibilities,” says Colorado Teardrops founder Dean Wiltshire.
“We estimate the Boulder will restore EV ranges to their pre-towing range, or better, and be used two or three times more than traditional RVs because it is so easy to take with you while also removing the anxiety of reaching the next charging station.”
There’s even a possibility of fast charging with the Boulder. Colorado Teardrops plans to equip the trailer with a CCS 1 socket and 50 to 60 kW per hour power output. The Boulder can also fast-charge itself at this pace.
“The interim plan for proprietary vehicle systems would be to provide the appropriate proprietary kit to match the customer’s towing vehicle, at least until we reach a point where there is a national standard,” explains Colorado Teardrops.
At a list price of $55 000, the Boulder is far from cheap, but that’s inevitable when one incorporates such a huge battery and focuses for the rest on lightweight, high-quality materials.
Trailers for extreme conditions
Colorado Teardrops builds teardrop trailers that are built to last generations. Designed and produced in Colorado, they make trailers for extreme weather and road conditions using high-quality materials and building processes.
Further, by focusing on ergonomics and a small footprint, the Boulder offers an enjoyable way to visit the great outdoors while avoiding overcrowded campgrounds and still be able to park it back in the garage when returning home.
The Boulder comes with an insulated hard-shell cabin and beds for up to a family of four, including a queen-size mattress and bunk beds, a dining lounge with couches, electrical outlets, and an exterior kitchen galley in the back. In addition, features such as a hot-water shower and interior climate controls try to offer comfort and a luxury camping experience.
Company founder Wiltshire believes that electric vehicles will disrupt the RV industry as much as the auto industry over the next decade. Less than 1% of EV owners have seen a luxury camping experience paired with an EV.
“The Boulder enables a return to the vision of a practical EV range and off-grid camping,” Wiltshire concludes. “We are working to ensure we maintain our highest standards for quality manufacturing as we scale to meet demand.”
