Suggestion for Repair center near San Antonio

[Hermannator]

I live near San Antonio and I can't seem to find an RV repair center. With all of the oil drilling activities in the Eagle Ford area is has swamped the area with RVs and campers. I can't seem to find a place to have my showhauler repaired in a reasonable period of time and I don't want it to sit for weeks at a place that does shoddy work. Any suggestions are appreciated.
