It's an absolutely beautiful drive and we've done it often with our 40' motorhome. However, if you don't remember it, from Dolores you'll have a steep uphill and from Ouray there will be an even steeper downhill. It just depends how you feel about mountain driving.
Be sure to check the website for Molas campground. They have recently redone it and have upped the prices. It's a very pretty setting.
As mentioned above, we too, always used the 'Mountain Directory for Truckers and RVers' when driving in the West. It's a very useful resource.
Have a good trip!
