What is the longest rv that with fit in a hookup site? Will a 32 foot RV fit?

Yes, all the time

I have a 30' trailer and I was able to put it in space 14, and that is the smallest full hookup site. The sites get deeper as they go up and I think the last full hookup site is 24 except for the four premium sites. You can put a 50' RV in those sites

Yes!

Yes. Most are not but ya no problem

50'
