If length is your only worry, it really doesn't make much difference until you get into things like gas stations and small stores, in town driving, etc. We usually refuel at truck stops, since there is usually lots and lots of room. You will need to watch for adequate turn areas. Most any of the newer camp grounds can handle long rigs. The longer the trailer, the easier it is to back up. Things don't happen as fast with longer wheelbases. Just for normal towing, you probably won't not any difference other than a wider turn radius.
