I can give you the shortest route but are you trying to avoid going over the highest passes?
285 down to 50 over to 550 down to Ridgeway. You will go over Monarch Pass which is over 11,000 feet, though. You'll also go over a couple of other passes that are below 10,000 feet.
This ^^^^^ "Best" is always subjective, depending on what one's point of view is. This is an easy drive, is incredibly beautiful, and worth it to see a goodly part of Colorado.
Taking US 285 out of Denver, it's 4-lane up to Evergreen. There's some twisties and turns, but not a significant problem heading up. There will be some hills, and ups and downs, and a fairly good "down" from Pine Junction down to Bailey; just let your engine help you and drop down to a lower gear. Certainly doable, RVs do it all the time.
From Bailey to Kenosha Pass is an easy drive, you'll be following the North Fork of the South Platte River up to Grant and then start going up Kenosha Pass. This pass is a "must see" when you get to the top. There's a parking area just over the top, a fantastic photo op to get pictures of one of the most brilliant views in all of Colorado -- South Park opening up before your eyes.
Dropping down from Kenosha Pass, it's a relatively flat drive across South Park to Fairplay, which is worth a stop to see South Park City, a collection of over 30 buildings brought there from other areas and tracing the history of the region with fascinating artifacts. You'll be at ~9000-9600 feet in the South Park area, so take that in to consideration; the air does get a little thin at this elevation, particularly for those not accustomed.
Along the way across South Park, you'll have Red Hill Pass just before Fairplay and Trout Creek Pass as you drop down to the Buena Vista area. Both are barely noticeable.
If you have the time, spend some time in Buena Vista -- well worth it! And also, further down the road is Salida, also worth spending some time there.
Monarch Pass is another "not difficult" pass. As mentioned above, at the top there's a gondola/aerial tram (the Monarch Crest Tramway) that takes you to an observation area. IIRC, it's $7 for adults/$6 for seniors (over 55). Another of those spectacular locations for a memorable photo op.
Dropping down from Monarch is Gunnison and the Curecanti Recreation area as well as the Black Canyon of the Gunnison NP. All definitely worth the time to spend there, if you have the time available. It's an easy, beautiful drive down from Gunnison to Montrose, where you'll pick up US 550 and head south to Ridgway. While staying in Ridgway, you could always double back on this route and explore the Gunnison Valley area, including the locales above.
Hope you have a safe and enjoyable trip!
