There are a couple of practical reasons why a campground owner would choose to exclude TCs:
1. Liability from jack failure/tipover with camper off the truck.
2. Removal/disposal of abandoned units. With a wheeled unit, all you need is a tractor or wheel loader and a chain to drag it away. A TC requires a heavy duty pickup truck, and are a pain to load for someone who doesn't do it regularly.
That's assuming it isn't some rot box whose jacks have collapsed. Now they've got a REAL mess to clean up.
Most campgrounds have some sort of wheel loader or tractor, but in my travels, campground pickup trucks are either old 1/2 tons, or have service bodies on them, and are generally loaded to the gills with maintenance junk. Some campgrounds don't have pickups at all. Their service vehicles are UTVs.
You're just not going to get very far dragging a TC with a wheel loader.
I've been told that these are BS reasons before, but when you realize how big of a cheapskate the typical campground owner is, you'll understand that anything they don't have to spend money on is a bonus.
TC's aren't that common so they figure they're not losing a whole lot of business.
