We full time traveled for 8 years. Seven of those years we had a chase car, a PT Cruiser turbo and i drove the International truck and pulled the 36 ft 5th wheel. The big truck would give about 7.5 mpg, the PT would give about 23mpg. I figured if we put 100,000 miles on the PT, it would come out to be about free as opposed to driving the big truck. We did a lot of exploring and seeing the sites in the car. The truck did its job of moving the house(trailer). In some occasions we had to either park the truck or car in another location on the rv park as the site would not handle all 3 vehicles. But the having of the car made the travels when out for the day so much better than the big truck. Some folks thought we were nuts because of the added costs. We drove the car 140,000 miles till we sold it. To us it was well worth it.
