Take a second look if your rig is larger than the campground's maximum size limit

When entering a National Park, National Forest, or State Park campground, do not be turned away because your rig is over the posted maximum size. In most cases, this limit indicates what size vehicle can be accommodated at ALL the campsites, though some--and sometimes many--will fit larger rigs. Before giving up, drive through the campground and look for these larger sites and measure whether you will fit. Remember that  overhangs can extend beyond the designated pad allowing larger rigs to squeeze in. Parking your tow or toad away from the campsite may also enable you to fit into the designated space. If there is a host or ranger on duty, ask about larger sites that are available.
