Do many campgrounds discriminate against TC's...?

Actually many RV parks do charge for size and power needs. My wife and I full-timed on a 40 foot diesel pusher for about 10 years. With the toad we needed a spot about 60 feet long and usually desired 50 amp power. We often paid more for 50 than 30 amp and several parks designated their longer sites as premium. . .meaning a higher charge.

But we bought the TC so we don't have to stay in RV parks, though I know occasionally we will.
