Just a word of caution - I've owned (in order) Subaru, Toyota, Ford, Nissan, Chevy and now my Ram. While I like my truck, without a doubt Ram's service departments are at the bottom of the list by a mile. Unless your truck is on fire or won't move there is nothing wrong in their eyes. Point being just because you don't like a certain dealer the one across town likely won't be any better.
In the whole grand scheme of things the crappy service is a minor annoyance and wouldn't even keep me from buying another Ram. My $$ goes way further with Ram and I guess they have to save somewhere. I just find it entertaining to listen/watch the service writers tap dance and lie out their asses to people every time I'm in for something. Everything is "normal" or "they all do that". Right up until it catches fire or won't move. Then maybe you can get their attention for some repair.
In my experience, all other major brand dealers hit stuff head on and take care of problems. Ram reminds me a bit of RV dealers where they either break even or lose a bit on warranty work and don't want it. Or, the grumpy guy in the office gets a bonus for turning people away.... or??? who knows.
