Sounds like the finish on the camper had already been maintained incorrectly before it became yours. The only way the paint would have held the staining from the mineral-rich silt or clay comprising the mud would have been if it was oxidized and chalking before the encounter. Taking advice from the forum members who haven't seen it could get you in trouble because paint that is that oxidized/chalking also strips very easily! My advice to you, as an extreme car guy whose has put many vehicles into car shows, would be for you to search out a highly recommended detailer in your area who advertises paint correction services. They will give you the honest answer if there's any salvaging of the finish. If you go to a body shop, they'll just want to sell you a paint job from go. Hopefully it can be salvaged for you! Happy Camping!
