Couple followed GPS stranded for couple days in 23 ft. MH

Just last month I was in my MH and my new GPS led me to a steep and winding road that became gravel (even though I had the 'paved roads only' option checked!) and then became one lane gravel for several miles before it led to the highway. Fortunately, it was early in the morning and no one was coming the other way because there was no place to turn around. :E From now on, I will always consult my Benchmark maps before I take any road directions.
