We did this route last summer towing a 7600 lb TT and it was fine. A good road but very few service stations other than the towns. Two watch-outs:
1. In Cortez there is a screwy Y-shaped intersection. From Moab to Durango you will be coming in on one of the legs of the Y. The tricky part is that the road goes from 4 lane to 2 lane in the intersection with no warning. We were actually crowded out and had to jump a curb to save the sheetmetal.
2. As you come into Durango on 160 there is a very long and steep downhill grade - The Mountain Directory West lists it at 4-5 miles of 6%. It's manageable in lower gear, but the hill just goes and goes with several gentle curves. Take your time.
