they can wiggle in and out of discounts fairly easily, I wouldn't worry about incentives so much just what you want to pay.....let them figure it out and walk away.....somebody will call back, and if nobody does call back than you went a bit too low, but think you be surprised at tricks they can pull....I was told by 3 chevy dealers I wouldn't qualify for discounts or incentives......I got a lease incentive and ive never leased a car in my life...sales people know! its the game they play everyday, who will pay the most and who wont.....i did almost all of my negotiating thru email and text, was a lot easier and i think you have better edge this way...… you still a good price for 2020, seems you can always get about 13k off a truck....see it happen every day for almost a year now
