Job master tailgate? W T F? Never heard of it. A standard tailgate if you need a replacement for a newer one is ridiculous enough.
I know a guy who bought a brand new denali truck last year. Their tailgate is also a $7k option. He wanted an otherwise fully loaded truck minus 2 options and he ordered the truck as it was because he wanted a certain color. Add the fancy sunroof, that's like another 3 grand on those. The dealer said that the truck as he wanted to get, would cost him like $2 grand less than a truck that had what he wanted plus those 2 things. Yet seperately these 2 options are $10 grand if added to a lesser truck. So since they wouldn't lower the price of the truck he wanted by at least $7 grand without those 2 things he wound up getting a truck that had everything he wanted plus 2 things he specifically didn't want.
