Charlie,
Welcome to the forum and good luck finding a camper! Sorry, can't help you on your location.
Oly has an Eagle shell with the heater and sofa options (plus a couple others). All the campers have the above cab bed. On the smaller campers (Eagle, Ranger2, Fleet), the width is about 69 inches and that bed is designed to sleep in length wise. With the sofa, you have a nice place to sit, storage underneath and an extra place for a friend to sleep. Plus a place for you to stretch out, without raising the top, while on the road.
With your truck, you should pay attention to the weight of the camper vs/ thegvwr of your truck. The shell models are lighter (until you start building in cabinets, etc). And if you go with a standard model with the cabinets remember that every option adds weight as well.
BTW - I ended up driving up to Idaho, from Denver, to get my 2000 FCW Ranger. FWIW - It is a long bed model that fits on my truck with the tailgate down.
Good luck with your search,
Jim
