Many years ago we had a 34 foot class A motorhome. While traveling to a new to us campground in Pa. after dark our gps sent us down a narrow dirt road to no where. After about a 1/4 mile I called the campground. They were surprised that the gps was still making the same mistake.
Fortunately I had a backup camera on that camper and was able to back out out without too much problem. With a trailer or no camera I would have been in a big hassle.
Another time with this same motorhome I reached a low overpass with no way to turn around. I backed up a ways and used the parking lot of a private golf course to make my was out.
