Home built vs Mass produced question

[heron]

In CA, near Encinitas where we were visiting friends, when I called a couple of campgrounds, they asked me the year and make of my rv, and when I said '88, they were appalled, and I was not welcome.That was the first and last time I had a problem, but I do have the coveted medallion on the old Roadtrek. Had we not needed a place to be for one night, I'd not have called, nor did I have any desire to stay in their snotty ass place. Though we'd been told that we'd be rousted at WalMart, we did anyway, off in the corner, showing no lights, and had no problem.
