TT When Solo....OR Truck Camper?

Camping this past week the people nearest us had a van camper. Every morning, they made breakfast, packed up their van and drove off, coming back that night. Until the 3rd night when someone else parked where they had been camping (not a reservation location). They drove in the area, drove around, then left to go somewhere else. Having a truck camper, if you went fishing, or just drive around the area, you could lose your camp spot having to find another one possibly every day. The advantage to a TT is you leave it, take the truck and come back to your camper after a day of fishing...
