For 23 model year 5.3 powered Sierra's, there is going to be plenty of discounts and incentives available through the end of this month.
Depending on where you live and supply, $12-14K is what I see available right now if you have a qualifying trade. 2009 or newer.
GM and Costco incentives alone account for $7k. Most dealers in my region are offering $5-6K in dealer discounts from MSRP.
High trim RAM 1500's - So many available, the original MSRP's are truly outrageous though. Almost uncompetitive with their competition. Limited series MSRP in the high 80's..... The Laramie's look to be a decent price though, Low 50's which falls in line with the comments of $16k off right off the bat.
