We have found that the major routes to all those towns are good for a 40' motorhome.Hwy 68 into Taos is good and even continuing up to Eagle Nest over to Red River to Questa is good. There are some ups and down but your MH would be fully capable of doing them. 68 doesn't have any big hills. Monte Bello is a nice basic place to stay. Great owners.
Hwy 84 to Chama and continuing on to Pagosa Springs is an absolutely beautiful drive. Abiquiqu Lake Corp of Engineer park is a pleasant place to stay. You'd be in the painter's, Georgia O'Keefe's, home area and she got lots of inspiration there.
Cochiti Lake Corp of Engineers is another good place to stay just south of Santa Fe. For an RV park in Santa Fe itself, Santa Fe Skies is probably the best.
From Pagosa Springs take 160 west to Durango, an easy drive. Plan to stay in Pagosa and soak in the awesome springs right in town overlooking the river. They are extremely clean concrete pools of varying temperatures. We usually spend a couple mornings there.
