Since DW travels by air to her work, there are many trips where the dogs and I will do the driving from place to place and then pick her up at the airport near our new stopping point. One trip we were on our way to stay near the grandkids in TN. The campground carefully told me to ignore GPS directions and take the second turn onto a road instead of the first (the road looped and reconnected with the main road). I looked at a map and decided that taking the first turn would shorten the trip a few miles, so that is where I turned. BTW, the dogs never objected.
It turned out that the road was over and around a small mountain/big hill with cutbacks and very sharp turns too tight to make with the motorhome and towd without disconnecting, and way too tight to even think about backing up. There was nothing I could do except disconnect the towd, drive the mh forward, walk back to the car and drive it forward, then repeat the process. It took several hours to get where I could reconnect and finish the trip to the campground. All the time this was going on the dogs never once offered to help. I think they laughed at me behind my back. I was several hours late picking DW up at the airport, and try as I might, I could not think up a plausible fib to explain my tardiness. I had to tell the truth. Even now, several years later, I get reminded of my "shortcut".
