Good Sam account representatives and Woodalls before them measure the 'usable width and Length', that is from the road to obstruction such as trees, from power pedestal to the next or to obstruction such as a hedge or fence. They average these measurements, show that in the listing. Remember its an average. Take note that only camps with a Good Sam rating have these measurements. Listed but not member camps claim their own facility.
Camps not rated use their own ideas, but on experience, length published is of usable level space for the rv., not necessarily total length where the tow can be parked in front, or width where the tow can be parked alongside or angled.
Our caution flag pops up when google earth shows short when rvparkreviews.com reviews dispute size
