Do you remove your camper from the truck while camping?

I take mine off sometimes. If I'm launching or retrieving the boat it makes it easier but I've. Sometimes if we're going to go to a zoo or amusement park I'll leave the camper at the camp site. It costs less to park a truck than and RV. Also, I don't like leaving the camper and it's contents unsupervised in a parking lot. I'd rather have it at the campground.
I can take mine off in about 15 minutes. Putting it on takes a little longer to get it lined up.
