Alignment Issue

[Greg S]

I have a 2021 3500 Diesel. I drove KO2's for 25000 miles and couldn't keep the truck aligned. Just bought Nitto Ridge Grapplers and STILL can't keep it aligned. It drifts to the right. The folks at the dealership have told me it's because of the crown in the road. In fairness, they test drove with me. I put the truck smack in the middle of the road and it stayed pretty true for about 5-6 seconds. If I'm in the first lane, nearest the median, the truck will drift UP into the crown; if I'm in the outside lane, it'll drift down and away from the crown. The dealership explained it's something about the way a Ram is designed that causes it to do this - I mean no discourtesy but, that doesn't make sense... Is this something standard to Ram's?? The have told me nothing is bent underneath; the tires are balanced and air pressure is correct. It's been adjusted to spec's and still, it want's to drift away! Any ideas?

The factory specs are too broad and dealers are too lazy, find a good shop and have it aligned to Thuren specs https://www.thurenfabrication.com/pages/2013-2022-ram-3500-alignment
