How far does the Trail Ridge mirrors extend? My current mirrors on my 2017 3500 Denali extend just three inches. That gives a total of 104 inches from outside edge of mirror to the opposite outside edge of mirror. I am looking for a set of mirrors that will give me 107 inches total. Trying to adjust mirrors to pull a 102 inch wide trailer leaves only one inch of usable mirror surface on either side.

I know it's a long shot. I've been searching for the last two hours. I need the part numbers for the top and bottom glass for the driver side on a 16 GMC 3500. Had a lady mirror slap me.

No.  Gotta either replace them with GM or pgamboa can do them.  84290982 and 84290965 for the OE harnesses.  Black mirrors are 84228899 and 84284596, chrome are 84284593 and 84691681.  Those mirrors are for diesel engine.

I see multiple mentions of adding these mirrors to 2500’s with the Duramax package.  Will this same kit and part numbers (harnesses and TR mirrors) work if I have the 6.0l gas?  I have a 2018 2500 Denali with factory tiny folding mirrors, and need to upgrade so I can tow the 5th wheel.

So I bought a set of OEM Gm tow mirrors with power everything for the diesel. Your saying I would still need to modify the harness to replace my OEM small style mirrors(power everything)?.

      I will be one of those "blinded". One, I like new shiny things. Two, I've never kept any of them beyond the 3/36. Three, I don't finance anything. Four, yep, it's a waste of money....so,what? I'm doing my part of keeping automotive industry going and keeping my neighbors, most of whom are in it, employed. 😉      By the way this is the "signature... ¬

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By marpel · Posted

      Although there is a "recommended" weight by those who sell trailers, my experience has been that they are way too aggressive in their information, for me at least. My '22 with 6.6 Gas, has a payload of about 3400 lbs and depending on your specs (I don't have 4WD so it has a bit higher Payload than others) yours will likely be different. Payload is one of the most important numbers for towing. Although you "could" tow the max trailer weight for your truck, I, personally, would not go close to that number. Having said that, a lot depends on how/where you will be towing. I live in the LMD of BC and often tow to Denver, Co, along interstates (flat and mountains) and I find I need to keep it in 5th (6spd) for the trip and travel at around 65mph. This is for a trailer dry weight of just under 3500lbs. If you are only doing local, short trips, it would not be that big an issue if you had a heavier unit. You will be surprised how much stuff you load the trailer with, so I would only recognize the trailers "full" GVWR weight rating, then decide on the appropriate trailer from that number. If you are worrying about how much stuff you should be putting in a trailer, you might have too large a rig from the get-go. Once again, depending on what terrain/distance in which you will be pulling. Marv

      Disconnecting Battery

      By marpel · Posted

      davester, Thanks for the response, how ever, I think I am now a bit more confused than I was before I posted - - After I posted, I actually found a YT video of a guy who replaced his Module (above tire) and he only disconnected the ground cable of the battery, but you describe rubbing the two cables together after disconnecting. I presume that is to do as you describe and eliminate any residual energy? - When I picked up the Module (between my posting and reading your response) from the dealer, I specifically asked about any re-programming and he stated it was not necessary as it was simply plug and play. Don't know how knowledgeable he is, though. - The video I watched also showed the Module plug to be difficult to "unlock" and remove, but there was no mention of silicone, although the video did show a bunch of dust/dirt in and around the plug (old truck) during removal. Are you talking about silicone that was applied by the factory, or silicone that you applied prior to plugging in? Thanks again, Marv
