I'm in the market for a new PU to tow my 13,000 gvw WW FSW 3200. The deals on the 2014 around here are $5000+ right off the top... a considerable savings. Trying to get more familiar with the new ...
One thing to consider is how long do you keep your trucks? The 2014 will be worth about $45K as soon as you drive it off the lot. If you keep your trucks forever get the best deal you can. Some 2014 models have about $8K in rebates and hold backs to move them. If it will be used for towing 90% of the time the trans improvements may be worth the $$$. I agree with others: Get the extended warranty with either if you go many miles. All the new diesels suck for long term reliability.
