You didn't say if you would be traveling solo or with a companion? I'm guessing no children? Cause truck campers become somewhat crowded when there are more than two . . .
One issue to consider is the overall height when the truck camper is on the truck. It can cause problems with low tree limbs if you are truing to get back into the boondocks. A really good answer to that - if you anticipate it would be a problem - is an Alaskan Truck Camper.
