Diesel vs gas for Class A....also length of RV....

As a ft I can tell you that most (not all) state and fed parks will not take a full size anything. These places are beautiful to visit but the designs go back to tent camping or small trailers from the 50, s . Use a Google maps, reviews before Choseeing one of these campgrounds. I spent over 2 hours getting my rig out of one these spots. Down a long hill no toad but when we got there it was ugly.
