Long Class A rigs with Trailers - Where do they stay?

We have done a lot of traveling all over, and so far have never had a problem finding spots to stay. 99% of the time we are in a pull through, however we have had to unhook trailer at one park we stayed. So if I have to unhook my trailer at 1 out of 100, no biggie.

Think about it, most parks have to have space to accomodate the big 5th wheelers that are usually pretty long. A 35' 5th wheel and the haul truck is probally 55' anyway.
