It's a well-known fact that towing a travel trailer can kill fuel economy, giving owners of gasoline- or diesel-powered tow vehicles range anxiety when traversing remote, hilly areas. Luckily, infrastructure for refueling is generally well established nationwide, allowing prudent adventurers enough opportunity to top off. For time spent truly off-grid, travelers have come up with plentiful backup solutions for carrying more fuel. For EV owners, though, traversing away from the beaten path with a trailer attached is not so easy, and even the beaten path is no cakewalk. Many areas do not have the infrastructure to support road-tripping, trailer-hauling electric vehicles.
