I would say if you go up into the mountians you would definalty want some good towing power. That is a chunk of change with a camper and a truck to tow. Don't know enough about campers though. But another option would be a motorized RV, then a tow package to tow a small vehicle.
Or even a tent would work out, providing you have an air mattress, and no one is afraid of the snakes like someone is here. Just saying.
