For a scenic drive and avoiding Denver from Black Hills you could work your way over to Casper, WY then south to Rawlins & west a short distance to 789 which becomes 13 in Colorado to Craig, Meeker and Rifle on I-70. Then east on I-70 to Hwy 24 toward Leadville and Buena Vista and on to Poncha Springs. From there continue south on 285 (or17) to Alamosa and Antonito and continue to Hwy 84. You could also go to Taos, NM before 84 if you want. 84 will take you into Santa Fe.
We've driven this route with a 40' motorhome towing.
Santa Fe Skies is the place to stay - very nice and convenient.
For Sedona we enjoy staying at Dead Horse Ranch State Park in nearby Cottonwood. Check out Jerome while you're there but not with your RV.
