Dry camping and riding in Colorado

Looking for a place to dry camp with 35ft toy hauler and ride trails with Teryx LE 4 seater. Would like to go in the area of Telluride – Durango – Silverton – Ouray area of Colorado. I would like to spend a week in one spot and be able to ride several trails from that spot.
Any recommendations or insight of area would be appreciated.
Thanks
