I can understand wanting a site that can accommodate your rig without worrying about low hanging branches and room for slide outs. As mentioned above, asking about the site dimensions will help. We have had travel trailers, fifth wheels and now a small Class A. I find it helpful to review the campground's website pictures and reviews written by others. We have found some great places with easy access that are not listed in any of the books --Good Sam, Passport, Woodalls, etc . Now that we are retired, we find non-holidays and traveling during the week is best and gives families the time and space they need on weekends. Check out Harvesthosts.com. It is a collection of wineries and farms that offer boondocking on their property. You are asked to offer support by purchasing their products. There is a small membership fee [$44]. If golf is your thing, try rvgolfclub.com. Enjoy....
