2gypsies gave you that info in your other post:
" Another route you might consider which is milder is from Ridgeway picking up Hwy 145 through Telluride and down sto Cortez. It's still mountain but of a more gentle kind! But then you'd miss Silverton unless you drive back up just in your Jeep from Durango."
I agree with that assessment, but you'll need to take 62 out of Ridgway to 145. Its longer, but still great scenery. If you have the time, take the spur to Telluride(145 doesn't actually go "through" Telluride) Have a great trip.
