I have been looking for a tent for a while and originally thought about a truck bed tent, but after seeing these roof tents it has me thinking. Do they make one that would fit on the roof of my Double Cab? I dont have roof rack so I would need to get some for the tent. This way i still have the whole bed for other crap, and will have a tent on the truck and not have to pack one, I work shift work and tend to do stuff at random.
