- length; overall, living, and combinationThe 2 common references to RV length are “living” and overall. When we shop for RVs the number we see in a model designation is the approximate living length. For example, an Arctic Fox 29-5E has an exterior length (Aprox. w/Hitch) of 31'. [northwoodmfg.com] Arctic Fox is one of the most realistic manufacturers when it comes to actual versus designated lengths, there are some that have a difference of more than 3 feet between the model designation and the actual lengths.
Motor homes like travel trailers (TT) have a larger discrepancy. For a TT the difference is between the box and that part of the frame, the A frame, that hooks it to the tow vehicle. Typically it is about 2½ feet.
With a MH it is the cockpit space that “can” be used as living space, but not well. And don't forget space between the front seats and the bumper. And, if it is a gas MH, then there is that pesky “dog house”, it is the bump up in the floor that covers the engine.
To make it even more difficult there is the combination length of the tow vehicle and trailer or the MH and the dinghy (toad is another term).
