Going from Buffalo to Ten Sleep on Hwy.16, Powder River Pass with 40' RV and towing a Jeep. Mountain Directory says it's a pretty good road with curves and steep grades. Anybody been on it?
Your 40' MH will do just fine on the road - ours did. Get in low gear before going down and you will only use your brakes a little. It'll be over before you know it! :)
