Get some of those hard plastic cutting boards (Dollar Store) and try to find them with a cutout handle. Tie a piece of rope through the cutout for ease when pulling them out when ready to leave. They are thin and easy to store if you don't have a lot of storage room for big blocks of wood.
We used public parks all the time - national, state, national forest, etc. and sites are rarely paved. Even if they're not required, we used them because of sinking in dirt or sand... and you will encounter this in public parks.
If you park anywhere on asphalt it's common courtesy to use something under your jacks so you don't make gouges in the asphalt - yes, even for a night at a WalMart!
I'll also agree with those who recommended that you slow down for this trip. You won't see the area if only spending a night or two. We full-timed for 16 years and traveled constantly and we still didn't see it all. :)
