I put a sled deck on a CC with 6'10" box. I went for a short deck as well but found there are different length of 7' decks. Many are too short and there was a space between the end of the wood(deck) and the tailgate so you can see into the box.
I looked and found one that covered the box completely but the loading bar is just shy of the end of the trailer hitch (so it does not make my overall truck length longer). It all depends on the brand of deck and even year in some cases. A full 6'10" of coverage was what i wanted.
Park and CHMSL is Off in all modes. all other lights work just as you have described (proper sequence etc..)
Thanks for the source to troubleshoot the burnt out light. Unfortunate if it was burnt from new.
Thanks.. yes I have the mirror lights as well. cargo light button seem to work for me on those as well as the rear box lights and tailgate light.
strange
Sorry for the simple question. I have a 2020 Silverado 2500 HD and I cannot figure out how to get the cab mounted cargo light to come one. The obvious button that illuminated the permitter lights, in-box lights, and tailgate light doesn't seem to turn on my cab mounted (up with 3rd brake light) cargo light.
Am I missing something or is this another delete from gm (e.g console storage, read map pockets,...)
