Just ordered a 21 Silverado trailboss crew short 4x4 with a 5.3. Black of course. Should have in 8 weeks. Hope they are right. Delays on supplies are hurting assembly plants.
Your rear window will be leaking within a year. Also keep an eye on engine noises, 1 in 20 of the 5.3s are having lifter issues. You can buy a dfm delete for about 200 bucks.
