Not much close to Vail. There are a couple of BLM CG's you might check out. Walcott CG is ~ 1.5 miles west of Walcott (exit 157) on US 6. A little down from the level of the interstate so you hear more river noise than traffic. Further west by Gypsum is another BLM CG. Exit at Gypsum and head west on US 6 (first roundabout on south side of highway) a little over a mile. There is a private CG (Riverdance RV Resort) a little further down the road. The Costco in Gypsum is usually the cheapest gas for many miles along this stretch of I-70.
