Dealers don’t know what the manufacturer rebates/incentives will be until they drop from Ram. They don’t have any prior knowledge.
If I had to guess, for a Laramie, you might be looking at $1,000 to $1,500 max in manufacturer rebates when they first hit the lots. Nobody knows for sure though. Typically, the higher you go up in Trims, the smaller the rebates. Like for Rebels, Longhorns, and Limiteds, they’ll probably only be looking at $500 (if anything) when they first hit dealer lots. Big Horns might be around $2,000 to $2,500.
