West of the Mississippi we've never had a problem with our 40' motorhome. However, we don't just see a road and take off. We research as much as possible, read others' accounts of the area, sometimes follow the road via a satellite image, stop at a ranger station and ask about conditions, and towing a Jeep we would sometimes disconnect before getting on such roads and scout it out first with the Jeep. If the road has a good gravel base we have no qualms about driving it with the RV. Of course, we don't travel over obstacle courses of big rocks. We always found wonderful spots to boondock, quite often surrounded by mountain views, rivers or lakes. We use public areas 90% of our RVing.
