When we go down there to and from Albuquerque we go 48 to 37 to 380 to I25. For you it will be a little longer but you'll make up for it after you get to I25. The trip over the Mountains north and west of Ruidoso hasn't been a problem for us in a 37 ft. Tradewinds with a small Suzuki Toad. It's a little steep and windy but we go slow and have never felt in danger. I25 is a great drive slowly ascending into Albuquerque and fairly flat until north of Las Vegas. From our reference of living in LA for a lot of years there isn't any traffic to contend with in New Mexico anywhere. Here in Albuquerque at the peak of rush hour, things sometimes slow down to 55 MPH through the only freeway intersection in town I25 & I40, so now real need to be careful of when you hit the wicked city around here.
Have a safe trip.
