Bought from Dave Smith (I think they're disorganized clowns) and had no troubles until I pulled one trailer (~5,000 lbs). Grinding noise in clutch. 5 star dealership replaced clutch assembly, but mis-installed some sensors, screwing up the DPF. 4 trips later, Chrysler finally took the time to fix it. Now, we are going through arbitration with Chrysler over the manual transmission in this vehicle, because it makes a horrible grinding noise (worse than any throw out bearing I've ever heard in my past 7 manual tranny vehicles). Chrysler won't fix it, told me I'm the first one to bring this problem up, but that it's normal (Chrysler's Star team). Chrsyler's service is second to all.
Stand by your products and honor your warranty obligations. Fix your substandard transmission and build a truck that's truly heavy-duty. Don't tell me that a heavy duty tranny has to have extra tolerance built in, which is why it's so noisy. Treat customers with the same eagerness after purchase.
