So, you are camping and you want to unload your truck camper

Those replies show how big variety TC offer.
It is huge difference between 8-9 foot TC with no slide used for hunting or fishing and then 12-footers with sliders who not only weight 3 tons, but create parking and handling issues.
Having big camper for my family trips, I was thinking about getting another small TC for business trips to other states.
But even pop-ups are not that light or small when you seek one with water tank and space for porta-potty.
I might just get camper shell and put mattress in it. :D
