Hello, I spent several months skulking around the discussion forums before recently joining TDR. ALL of you are responsible for my decision to buy a Cummins instead of a PowerStroke or a V10. I only haul a two-horse bumper pull, but six years of white knuckle driving out of the Verde Valley with my half ton made me realize I wanted something more. Now that I have made the plunge, I wonder if I am in over my head because I have zero mechanical knowledge and will therefore have to depend on others to make sure my beast is well cared for. This is where I hope those of you in the Phoenix area can help. The truck is still under warranty, but I am quickly learning that going to the dealer probably isn't the best idea for basic maintenance such as an oil change. I can't do it myself like most of you out there, so I need to find a place with someone I can trust who knows what they are doing when it comes to a diesel truck. Ideas???
