Sandy,
Not in the one year we had our hybrid
we did stay at some "
RV parks" in Iowa and Missouri
(to us an
RV park is designed for TT and the big class A's (bus like)
RV parks always have full hookups and usually cable TV)
In the seven years with the PUP we were never refused either (and we went to a large number of places both in and out of state)
I supoose there are some that don't like hybrids and PUPs but there is always the next place.
(BTW in planning we use trailer life and AAA and they usually say if limits apply) and KOA takes all campers
