I too wish they had something for every campground. I will agree with others that the sites are not always the size as advertised. Usually I find that a park has one size listed, but if you get there you will see there are sites much bigger than the max shows. I usually will check on google maps and see what is parked in the site I like or around the campground. Usually you will see there are 35ft RV's in spots listed as 25ft max. I have never run into a problem by looking at the sites and making reservations for a smaller site than I should be able to fit. I know that it could bite me, but it hasn't yet.
