You can negotiate a discount on any truck at any time. The size of the discount, however, will depend on your negotiation capability, time of year, and just how bad the manufacturer/dealer wants to move product!!
In April, I ordered a Ram Laramie fully loaded that listed for $50K and paid $43K plus license/taxes/registration. This was a ok deal as some have done better, however, we were pleased and luv the new truck!
I negotiated with 3 dealers within 50 miles from our home and never stepped into any of the dealerships until after the deal was done on the internet. Took a couple of weeks yo get everything done but was time well spent.
