Some cool campers in this thread. I bought this 07 Vista Cruiser B+/C last month. Its built on a Freightliner 3500 cab/chassis with the MB 2.7 liter diesel. I averaged 16 mpg coming back to Virginia from Florida @ 75 mph. Nothing like being able to wake up to a sunrise on the beach. Small enough to drive into downtown Savannah and park on the riverfront. However I just spent a week camping in Death Valley/Eastern Sierras (not in my camper). One of the guys in our group had a camper top on a 4x4 PU and thats definitely the way to go if you want to go off road without towing a Jeep.
