I installed a small cab over camper on my 04 ext cab 2500hd it comes over the cab half way. there is about 8 inches from truck roof to underside camper. when I meet on coming commercial trucks or high winds the center of my cab buckels in and makes a very loud noise. is this normal or should the roof be fastened some how? I can push down on center of roof and make the same sound,is there adhesive broken loose inside etc. I notice on crew cab trucks there are ribs formed on top of roof to give strength? any ideas!

With a prior roof strobe mount I used to have it used to cause my roof to make alot of noises on the highway. A few years ago I bought a new strobe mount, and this one allows air flow to go under it. Have never heard the roof make anymore noises. I think what is happening here is my older strobe mount caused restriction and then it would cause the roof to make that noise. I never popped off the head liner, but I would venture to think that the roof may lack support brackets or something, because i had the same strobe light mounted on a F250 and the roof never made any noises from buckeling. I think your camper causes the wind to be blocked and forced under that small area. Maybe if you could make some sort of reflector sheild to help with areodynamics, you could stop this from happening. You see alot of big rigs that have this angled sheild on them which helps with air flow by redirecting it in a more areodyamic way.

 

I would be concerned about having the roof buckeling over time, that it might cause paint to become damaged from constant flexing, especially in different temps.

Yep, one of the complaints about my previous ex cabs. That buckling sound on rough roads. Problem is non existent on my crew cab thanks to the ribbing on the roof.

Get used to it.

 

Or find a way to keep the air from getting between the two. Add a skirt to the camper maybe. I only have this problem when I have my windows down and it is super windy outside. Even then it's only occasional

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
