Ron here. Mom called me today. She is east of El Paso right now, headed to Fort Worth. She said it is very, very hot. Like 107f hot. She said that the A/C is barely able making a dent.
Climbing the steep grades of western Texas with that heat is making for slow going. Since the RV is so heavy, she has to turn off the A/C on climbs, and drive slow. She said she is going to rest for a while and resume the drive at night when it is cooler.
