What kind of rv do you have? Can it pull long mountain climbs? When are you leaving AJ? If you are going up near I-40 soon, watch out for Snow, Ice, Remember Black Ice! I would consider staying a bit South until at least mid-April! Pieere

Widest and straightest roads are 202W to 101N to I-17N to I-40 east with lots of traffic on 202 and 101 and a big climb on I-17. The most scenic route is US60 East to I-25 north in New Mexico but you can also take 77 North to I-40. US60 and 87/260 are curvy mountain roads but doable.
