We are beginning to look at travel trailers. One consideration is the cost of towing the unit. With the Middle East situation and with the government saying that our highways are seriously underfund...
Not much difference for several reasons. Frontal area wind resistance is close to the same for them as a big trailer, usually they're towed with a smaller truck that has to work pretty hard to tow them are a couple of those reasons. If you need better fuel mileage look to one of the folding trailer models like Trail Manor, Hi Low etc. Those have some real savings possibility.
