30-32' TT - Are they too long, difficult to park, etc?

ours is over 32ft. as for campgrounds, yes we have found some that we can't get into. but we have so far always found another campground close enough to where we wanted to be that it wasn't an issue. and our first choice of CG is forest service, county parks etc. last on the list are private RV parks, which virtually always can accomidate us.

so, yes length can be an issue for a spot. for towing and backing, I'd rather back my 32ft than my 14ft cargo trailer. much easier to back into a spot.
