The growth of the EV market and the rising popularity of RVs are starting to become an intriguing market for EV-friendly RV products, from all-electric RVs to ultra-light camping trailers. As Colorado Teardrops is previewing, this market will also include teardrop trailers that double as rolling charging stations. With as much lithium power on the chassis as a Tesla Model 3, Colorado’s new bouldering camper can charge its towing vehicle enough to compensate for the decrease in range on the trailer hitch, allowing adventurers to disappear into the wild and return without an incident.
Battery-powered camping trailers have been appearing for several years, which are intended to increase the capacity and range of the electric towing vehicle. Some advertise starting a Tesla with just enough juice to (hopefully) get to the nearest electrical outlet. Others come from the more ambitious goal of self-propelling the trailer wheels in order to reduce the effective trailer load to zero, but these only remain prototypes.
With the offering of the 16.3-foot (5 m) Boulder trailer, Colorado Teardrops steps into the ground between these other electrified trailer concepts, giving the trailer the battery power to charge the towing vehicle enough to make up for the energy lost in towing, if not more than make up for it. This is essentially the same end goal as with self-propelled electric powered trailers, but without the e-drive hardware or software. Colorado Teardrops plans to equip the Boulder with a DC fast charger for quick and convenient electrical transmission.

“The ability to bring an electric vehicle back to its original range and provide recharging through renewable energy will expand camping opportunities well beyond its current range and enable a new level of eco-friendly camping,” said Dean Wiltshire, founder of Colorado Teardrops, of the inspiration of the boulder project.
Colorado Teardrops isn’t reinventing the wheel when it comes to battery placement, borrowing the popular flat-mount underfloor chassis integration from the EV industry. This setup promises to keep the trailer’s center of gravity low and completely avoid the residential facilities above.

The trailer has a light, insulated hard shell structure above the powerful chassis. A 3,500 lb (1,588-kg) torsion axle holds all of the battery weight, but at 1,950 lb (885 kg) dry the boulder isn’t particularly difficult to start (a lack of standard equipment is critical there).
The convertible interior has a dinette that converts into a queen-size bed measuring 60 x 78 inches (152 x 198 cm) and two bunk beds, so that a whole family of four can sleep in it. Two floor-to-ceiling double doors make it easy to get on and off and, when open, offer plenty of fresh air and landscape.
The Boulder kitchen is delivered as standard as an empty space that must be filled in by the buyer to keep the basic weight of the trailer down. The layout is derived from Colorado’s Mount Massive Trailer and has a double opening, with a worktop and cabinets directly in the tailgate and a lower storage space behind two doors. When open, the doors serve as shelf supports and provide additional workspace and / or a table for a stove. Colorado plans to offer tons of galley options, including an induction hob and fridge / freezer that can run on the trailer’s ample battery power.
The galley will be empty by default, but Colorado plans to offer the usual features as options
Other options will go beyond the galley, and while some of them will require an LPG tank, Colorado claims to be exploring electric air conditioning and heating alternatives to keep the trailer fully electric, much like the competition right out in Colorado Campworks. Solar charging will also be available as an option.
As for the weird shape, which isn’t quite a boulder, not a tear, it seems to be entirely aerodynamic-driven. The side walls are sloped inward to narrow within the width of the towing vehicle, and the flattened top prevents the trailer from climbing unnecessarily high. The interior measures 55 inches (140 cm) to the ceiling.
As the renders likely indicate, Colorado Teardrops is in the early stages of Boulder development and specifications are subject to change. We certainly hope that the exterior design will change as the trailer evolves, as the original Colorado design really destroys the organic beauty of the traditional tear, which is especially problematic for a trailer with an MSRP of $ 55,000. We envision it could better attract well-heeled, EV-driving first-time users with a prettier, more polished design and perhaps a glamping-grade standard package of trim.
Any trailer will degrade the efficiency of their towing vehicle, but Colorado Teardrops plans their boulder to make up the difference
Colorado Teardrops is now accepting reservations at discounted rates for those who don’t mind taking the leap of faith. The company hopes to ship the first models within a year, but readily admits that ongoing COVID-related supply chain problems could postpone this … as does the process of developing and safety-testing a portable, viable battery pack.
