Unless you are really opposed to passes or have done Raton Pass and don’t want to repeat I would do as IDman suggest. I towed our 5er over Raton Pass going and coming every year 2007 thru 2014 going to CO and back. A bit of a tug as you get near the top but not for long. And good interstate. And Raton to Clayton is good highway.
We always stayed at Fort Amarillo RV on west edge of Amarillo as it was close to restaurants and shopping if needed. But been a few years ago. Many seem to like Oasis RV a little farther west of Amarillo.
