OOOO yeyah... Fall river road is kick ass. TONS of great wheeling out here. Old mining roads, lots of BLM, old mountain passes. We took my buggy over mosquito pass before it had the turbo. The carb had a hard time at 13,000ft so hopefully you're fuel injected or turbo or rejet that carb before the trip! You'll need those 37's if your truck is full sized. The wheeling can get as gnarly as you want. there are some good books for wheeling in CO, or just get a CO gazette that has all of the trails for the state in it. We went from glenwood springs to breckenridge on off road trails. CO has some of the best and most accessible wheeling in the US for sure due to half of the land being owned by the state or the govt.
