I would reccommend that way. We drove that route in 2005 and found it to be a nice shortcut between I-35 & I-40. For the most part it is two-lane and goes through small towns with lower speed limits but not many traffic lights, as I recall. Fuel was no problem as most small towns have a gas station. Seems like most folks (farmers/ranchers) out that way have a diesel P/U so you know the stations will have diesel pumps. Many stations were easily accessible just off the roadway in the small towns.
FWIW - we stayed in a nice, convienient CG in Dalhart, TX called The Corral RV Park. Wide, flat gravel sites - some shaded - with FHU.
