My 24 foot conventional trailer tows longer than a 35 foot 5th wheel and I camp almost exclusively in NFS, State and Federal CAMPGROUNDS and only very RARELY in RV parks. Not sure what you mean by 'a lot of these campgrounds" since every campground is individually designed. They come in all different sizes and of course you will find a lot of SITES that are too small for your trailer. You will need to take it on a case by case situation. If you can't fit in local campgrounds there are always a lot of disburssed areas where you certainly fit if you can get there. Those are my favorite types of places.
Good luck / Skip
