OK, I have a '05 Dodge Cummins 2500HD. It's not going anywhere. I will say though, the A/C in this model truck leaves a lot to be desired. There are common duct/door problems, which I have not had, but the design really hampers the A/C.

What I'm considering is replacing my '02 Chevy. Bought it new, 2WD, 4.3. It has been almost trouble free. I did have to replace the intake gasket last year, common problem on that engine. But, looking ahead of getting something new before I retire. My Dodge is a 4WD, so for this truck it would be a 2WD commuter type. I like an extended cab and a short bed is fine too.
