5th wheelers size and frequent relocation/campsite fit size?

As a previous post pointed out, there is no standard way of measuring the sites. If it might be close, call the CG. My fiver is 32'. On a recent trip the state park web site said their sites were all 30'. I called the ranger, who gave me a list of site numbers which could easily accommodate a 35' or larger rig. The ranger also assured me that there were no tight turns or low hanging branches.
Had a great stay.
