My thoughts are 'too much time in a MH with those boys', how about picking up the MH in Albuquerque, NM, head straight to Mesa Verde NP, not much else around that area to keep the boys interested, the train from Durango to Silverton might be a good option, then head west via North Rim, Zion, Valley of Fire, Nevada and drop the MH in Las Vegas, hop on a flight to San Jose. CA, rent another MH and head west to Santa Cruz, Beaches, Boardwalk -fun things for young people, then after a few days head down the coast to Monterey, Big Sur and points south, I'm not sure how you can avoid going through the Los Angeles area (maybe midnight) to get to southern Ca Beaches etc. to San Diego to turn the MH in and fly back home.
