Motor Home is a little different than towing a trailer, but the decision to stop or continue going can be determined the same way regardless. Two factors:
1. Know the limitations of your own rig and the limitations of our previous experience. (If your better judgment says "stop" and wait it out, then do it!)
2. If you see the big-rigs (18 wheel trucks) stopped, then that's a pretty good indication you better stop too. They are the experienced over-the-road drivers who are "out there" for a living. If they stop to wait it out, with their experience, then you better stop too. I take my cue's from the truckers with a lot of traveling we do. Watch them, (not other 4 wheelers out they ... they are just plane crazy), watch the 18 wheelers and follow their example.
