2022 HD trucks delivery date

If you don't need the truck why are you ordering it?
If you do need it why would you want to get 4 months in, cancel the order and start all over again?

As of mid July, Ford had over 60,000 2021 vehicles built but parked around the country awaiting chips. I assume Chevrolet and that other brand, Dodge Ram are in the same boat. You are probably correct on getting your deposit back. I would think the big 3 will have to heavily discount those parked units to move them once regular production and chip availability resumes.
