I ordered my 2022 GMC 2500 Denali diesel July 06, it was built August 19, delivered to dealer September 2nd, delivered to my office Sept. 3rd. It was not supposed to have rear heated seats but it does.
That does not solve the problem.
I put a switch on mine, when I tow a trailer the tailgate and midgate is inoperative.
Cost $3 and 15 minutes of my 13 y/o Son's time.
Yes I have the finished prototype product my son designed. He sold the design to an aftermarket customizing company.
They are still in the preliminary planning stages of production. No ETA of when they will hit the market.
They were trimmed after driving 2380 miles. Highway MPG is actually improved .2 MPG, calculated over the last 5500 miles.
Truck has 7800 on it as of today.
Yes, I'm aware of the aero effect theory, they were taken off last month with no loss of MPG or ill handling effects afterward.
His prototype turned out so well, a very prominent aftermarket company purchased the design from him.
It looked stupid hanging down begging to be ripped off, seems like I'm not the only one that thinks so.
The truck looks so much better/cleaner without them.
