About the seat situations:
I'm about to go pick up a pair of drivers seats from two Denali trucks.
All power, all leather, heated, cooled, about 600 bucks for the pair. Just a suggestion.
I'd never buy a seat I didn't have many many hours of test drive accomplished.
(the Lincoln 30way power seats have the controls on the door and I don't trust the wiring to not be body integrated or we'd have lincoln seats right now.)
Ordered these to do a bit of customization before we put the seats in.
