According to Rams website, they are offering "up to" $11,000 off a 3500 Limited. Looks like they are offering "employee pricing" plus $1000 customer cash. I wouldn't offer MSRP for the truck, I would negotiate at least to the "invoice" price (which we know still includes holdback money for the dealer) and THEN take any rebates or offers.
Without knowing the exact details of that particular truck its hard to give an exact guess at what I'd offer. Go to Edmunds True Market Value and see what they suggest as a good price. I always offer some percentage less than the "invoice" price before rebates and haven't had to pay more than "invoice" before rebates.
For whatever reason it won't let me select a DRW with a diesel engine. I'm not sure what I'm spec'ing incorrectly, but whatever. At the end I am able to "build" a $68,700 MSRP truck, with "invoice" listed as $64,400. That indicates to me that they can take at least $4,000 off your $83,000 truck, now making it $79,000 "invoice" price. With "up to $11K" in rebates available off that $79K price, $68K is looking reasonable as a starting point. I'm sure that you wouldn't qualify for all the rebates so they will negotiate up from there, but that seems like an educated place to make a starting offer.
