Abilene is a great state park with lots of space between campsites. We reserved #83 which was listed as a 25' site. We have a Class B with a very low clearance and could not make it up the steep incline to the pad without damage. Park official drove by while we were figuring out what to do and had us move to site 84. Still had an incline but we were able to get onto the pad by using some of our leveling blocks to raise the front end when backing onto the pad. Once on the pad, it was completely level. Used the blocks on departure as well.
