i agree about a motorhome doing okay on those roads, or truck campers as well. The problem with a towed vehicle riding on wheels in the middle of the carriage is that the potholes twist and turn it with the exaggerated force of a teeter-totter. For example, I forgot to mention that one series of potholes caused the left rear of the trailer to hit the ground with enough force to break off the stabilizer jack in that corner. We have towed our trailer up the Dempster Highway in the Yukon (all gravel and dirt), the Top of the World Highway from Dawson City to Chicken (almost all gravel and dirt) and on the washboard and potholed gravel road into Chaco Canyon, all without incident. So we had no qualms about tackling these roads, but they were indeed much worse and, of course, much longer!
