Bowlus produces some of the fanciest custom hand-built camping trailers you can buy. The brand unveiled its pet-friendly Terra Firma model last year; now, Bowlus has announced that its slippery travel trailers deliver impressive performance when towed by an EV.
Testing with a Tesla Model X pulling the Bowlus Terra Firma showed the Tesla still retained 71% of its 333-mile range while towing the 3,200-pound trailer — thanks to a combination of the Terra Firma’s light weight and its aerodynamic design. That’s the sort of range that could make road-tripping with an EV far more workable than many other heavy trailers.
Towing is a major downside to camping trailer life

You can solar-power the trailer, take it off the grid and make it eco-friendly. But that’s typically countered by using an inefficient combustion truck or full-size SUV to get there, consuming extra fuel while under a heavy load.
EVs are a natural solution, right?

Sort of. EVs have a lot of torque and typically have excellent towing capacity. But trailers — often not exceptionally aerodynamic — can hit the range hard. Paired with the sub-optimal fast-charging infrastructure, it can make towing with an EV an absolute nuisance.
