The future of the automotive industry is electric. Trailer companies are gearing up.


The electric vehicle revolution is just around the corner, and automakers aren’t the only ones feeling the pressure to embrace a new type of transportation. With EV sales growth In the United States, accessory companies are also adjusting their strategies in the blink of an eye, retrofitting all sorts of products, from cargo carriers to charging stations, to meet the specific needs of electric vehicles.

For motorhome and trailer brands, one of the challenges is to evolve products to better suit vehicles with relatively limited ranges compared to gasoline-powered cars and trucks. That’s the problem trailer company Colorado Teardrops is trying to solve with its new Rock model, which acts as a portable charging station for electric vehicles. The product is currently in the prototype phase, but it is already creating quite a bit of buzz.

While electric vehicles can technically towing conventional campers, the weight and drag significantly reduce range, Colorado Teardrops founder Dean Wiltshire told OBJ. The solution his company landed on is to allow users to partially charge their electric vehicle overnight using the motorhome’s built-in battery, to negate the loss of range due to towing.

“We care about the planet and really see electric vehicles as a big part of the future,” Wiltshire said. “But range anxiety is real, and we knew we had to find a way to undo the loss of range from towing a trailer.”

With this latest move, Colorado Teardrops joins several other RV and motorhome manufacturers who are currently working to future-proof their businesses through targeted innovations in the EV space. Airstream is currently testing its electronic flow electric transmission that will help propel trailers and improve mileage for electric and gas-powered vehicles, and Winnebago is preparing its E-RV motorhome for the market in 2023.

Trailer Specifications

The Boulder will be released next year at a starting price of $55,000. The 11-foot-by-5-foot model, which has a dry weight of 2,200 pounds and a tongue weight of 185 pounds, is aerodynamically designed to reduce drag and includes a 75 kWh battery bank to transform the unit in charging station for electric vehicles. .

“Our test tow vehicle is the Tesla Model X,” Wiltshire said. “We have determined that if this vehicle has a range of [about] 300 miles, the Boulder carries enough load [to increase that to] about 330 miles. Actual range when towing is determined by many variables, but in this case we see the Boulder adding about 10 per cent more range beyond the full charge.

Colorado Teardrops is currently accepting deposits for the trailer and offering discounted pre-production prices.

“We’re excited to have a prototype built and know everything is working as expected,” Wiltshire said. “The pre-sales have been excellent and show us that we are on the right track with this concept. We see customers planning to order EVs soon and want to be ready for the camping season next year. The whole electric vehicle industry looks very strong.

The Boulder sleeps four with a queen-size bed and two bunk beds that fold up into bench seats and a table that lifts off the floor. The rear hatch lifts up for storage and features a 37 x 60 inch galley counter. Gullwing side doors create awnings, and the trailer is fitted with 27-inch tires with 10-inch clearance. Wiltshire said the Boulder is not designed for heavy-duty off-road use, although the brand’s upcoming models are.

“It will be great for national park campgrounds, festivals and enhanced areas like that,” he said.

Wiltshire has confirmed that the company next models in preparation, the 17-foot Denver and the 27-foot Golden, will both have adjustable roofs that can be lowered on the road (to maintain aerodynamics) and raised at camp to allow users to stand up inside. Both will have increased battery storage to fully charge larger EVs such as the Ford Lightning F-150 and GMC Hummer EV. These future models will allow direct DC connection from the trailer to electric vehicles while driving, enabling on-road charging for extended range, Wiltshire said.

“That’s nirvana for us: being able to charge while you drive to increase range,” Wiltshire said. “We want to help make electric vehicles even better.”
