www.traildamage.com is a great site with excellent trail reports with pictures, ratings, etc. Just go to "Trails", then look for the Colorado trails with the county name where you want to wheel.
Ouray County trails that look reasonable for your stock CRD:
Corkscrew Gulch
Engineer Pass
Governer Basin
Yankee Boy Basin
San Miguel County:
Black Bear Pass
Imogene Pass
Ophir Pass
San Juan County:
California Gulch
They all seem to be more scenic trails than anything out there. Those are all I could find on trail damage, and since I am not from or wheeled around there, maybe you will find more trails not on that site.
