Bryan,
This should be a relatively easy diagnosis and repair for a good Cat dealer. What I would look for is a true Cat dealer for trucks, the larger the better. There are places with Cat signs out that are not true Cat dealers. One sign of a good size dealership is if they have a second or even a third shift running. Those dealers have seen it all. I am not familiar with Texas Cat shops. Take a look on the web, you can google map and see how large the shop and lot is.
Smaller Cat shops may be fine also, just my thinking is there is more talent and experience to call on in the larger shops with lots of years of combined experience. I had a good experience at Patterson Cat in Denver if you happen to go that way.
