Of a Truck/Camper(that with kitchen/bath) combo with high MPGs. Now, I'm assuming it's going to be diesel, but I'm also curious what one can get on the half-ton campers.
You could drive a Prius at stay at Motel 6, that would give you great gas mileage and a tiny bathroom also. I manage 12-14 MPG from 55-65mph with a diesel F-250 and an Arctic Fox 865. I drive right past Motel 6.
