When Driving Class A What Route....

Consider that virtually every road was built with large machines and trucks so motorhomes will fit though some have made me pucker up some. I have encountered two or three old underpasses that I could not fit through and one bridge where I was overweight but shot it anyway. I have bumped a few limbs but not too many and I have used my coach quite a bit for attending horse competitions that are generally held way out of town. Ironically, some of the tightest roads that I have been on are the last leg of a journey getting to campgrounds(government owned) that were built 60 or more years ago when a family station wagon was a large vehicle and they don't seem inclined to widen these roads any. A truck GPS would probably be a good investment but I keep finding more urgent uses for my money. It is a good idea with any route planner to review the route. MY biggest issue is that my coach sits fairly low and I have drug the ends several times going in and out of parking lots but I don't know of any navigation device that would help with that.
