Presume you'll drive I-10 from Florida to Arizona (??). If "yes", I recommend RV Masters in Houston
or Trucks and Such RV Repair in Rosenberg, TX (far west side of Houston and south of I-10).

Recently my dashboard blower / motor failed (bad bearning) and had to be replaced. When I contacted RV Masters, they told me they had a 3-4 week backlog of repair requests. And they were experiencing 4-6 week delivery times for some parts.
So, I took my coach to Trucks & Such RV repair which only had a two week backlog of repair requests. Fortunately during that two week wait time they were able to find a new blower/motor assembly. I also hade Trucks & Such perform my annual maintenance (engine oil & filter, change fuel filter & fuel filter/separator, lube the chassis) plus change my engine air filter and air system dryer cartridge (it had been 2-1/2 years since those items were last changed). All of the work was done very well!
Both RV Masters and Trucks & Such have been able to retain all of their technicians by increasing their total compensation. Not surprisingly both businesses are passing on their higher staffing costs to customers meaning their labor rate have increase from $135/hour pre-Covid to $150/hour today!
Hope this info is useful. Safe Travels !!
