Hello Pepper and wife,
Everybody has given you great advice. We worried when we bought our 36ft Big Sky but love the open space and roominess. We've found that a lot of the older RV parks have smaller sites and that the newer ones have modified their campsites for big rigs. Length is not usually our biggest concern--we always check (by phone or books mentioned) for the width of the sites to accommodate our slideouts. But since we usually travel making reservations in advance we check on all this beforehand and have had few problems. And we have found some good suggestions for parks right here on the MOC website.
