I just want to add a little to what Tim and Michael have already pointed out.

Michael is right, you’ll definitely need winter camping gear. It can get very cold at night in northern NM and AZ, especially at the higher elevations. Here’s a map showing average annual snowfall in the US.Originally Posted by Midwest Michael
Even though you'll be farther south, you'll still need to expect cold temperatures (especially at night) and you'll need winter camping gear even in places like Oklahoma and Texas. It wouldn't be at all surprising to see some snow or ice at some point of your trip.
