This is our first road trip in a 40' RV. Starting with the northern route through the Dakotas to Glacier and down to Yellowstone and coming south through Utah national parks into Colorado, I'm looking for input from members as to any potential problems driving an RV of this size across the Rockies with a driver that has some significant fear of heights. We'd like to visit Rocky Mountian Nat'l Park, Colorado Springs, Pike's Peak and take a ride on the Durango - Silverton Narrow Guage RR and fit Mesa Verde Nat'l Park into the mix. I'm struggling with planning a safe through route and wonder if staying put in one spot, say Colorado Springs, and taking daytrips would be more practical. Focusing mainly on the Colorado segment but if anyone thinks there might be a problem with the rest of the route, I'd welcome your thoughts.
