Sunroof replacement

Anyone have experience with a full moonroof replacement on their F150? What was the cost? Mines a 2018 model.

I bought the truck knowing it had an issue with opening fully and they gave me an IOU stating they would cover all repairs so i could still drive it while waiting for parts. Now it wont seal properly. Its been 2 months now and "the parts are on backorder" go figure... dealer is offering me 1k and to seal the sunroof. I'm guessing the cost to repair for them will be much higher so they're trying to screw me over.

This appears to be an extremely common issue and the dealer just doesnt want to deal with it.
