Hi Everyone, Wondering what size extension cord to use, Length and Gauge, to use in the Truck Bed Power outlet on my 2021 Silverado with the Duramax Diesel. I would like to run an Electric Hedge Trimmer ( 4.5Amp ) and an Electric Chain Saw ( 4.5 Amp ). Thank you.

Thank you

Thank you

Thank you UWSkier.

Happy 4Th of July to everyone, Question on Tire Air Pressure when towing a travel trailer. My 2021 Silverado 2500HD crew cab with the Duramax Diesel calls for 60 psi in the front tires and 70 psi in the rear. I am running the factory Michelin AT2 tires. My travel trailer has a GVWR of 8,400 lbs when towing and I'm running factory installed Goodyear Endurance tires at 80 psi per the label on the side of my trailer. I live in southern Arizona and tow when the temperature is hot, 100 to 110 degrees. Towing when the air temperature is 100 to 110 degrees is it recommended to keep the tires psi at the manufacturers settings or because of the extreme heat build up is it safe to deflate the tires 5 lbs or so to eliminate /reduce air pressure build up ? I monitor the truck and trailer tire air pressure when driving and am wondering what is the safest tire psi when towing in extreme heat. Thank you .....

Hi Silverado4x4, Thanks for your comment. Yes I did check the bass and treble settings and they were good. I'm thinking there is a loose speaker connection somewhere because when I drive over rough roads the sound comes back to normal and then cuts out again. Thanks again !

Hi Everyone, I have a 2021 Silverado 2500 HD, LT, Crew Cab with the DuraMax Diesel. Lately the radio sounds "Tinny" and the "Base" sounds terrible. Wondering if anyone has experienced this ? Any suggestions/ideas would be greatly appreciated. Attached Photo is from the Internet to show what I have. Thank You !

Thank you all. Another member had this same issue and other members told him what to do. I pressed the Engine Start Button for 5 seconds with my foot off the brake pedal This allowed me to re-set the Fuel Filter Life to 100%. I confirmed this by starting the engine and it was Re-Set. Thanks again !!

Hi Everyone, I just had a new Fuel Filter installed at my Dealership on my 2021 Silverado 2500HD with the Duramax Diesel and the "Fuel Filter Life" on the DIC will not Re-Set to 100%. Would appreciate any help, info. Thank you

Thanks Wxman, I appreciate your reply. My symptoms are exactly what you experienced. I was talking to Lippert about this and they mentioned a lot of what you just said as possible causes. They gave me a Case Number for Warranty Authorization. They seem like real nice people to deal with. I'll post what the cause was after the dealership looks at it. Thanks again and Happy New Year to you and yours !

Hi Wxman, Thanks for replying. 2 issues regarding my post: 1st: The "Service Trailer Brakes" message was a bad 30 amp fuse for the brake controller. It's been replaced. 2nd: The notice I'm getting now says "Check Trailer Brake Wiring". This message comes on when driving and then switches to a different message that says "Trailer Brakes Connected". The trailer brakes work fine when this is displayed. The messages keep going back & forth between the 2 with no brakes when "Check Trailer Brake Wiring". Leads me to believe your suggestions ( Loosened magnet, connection, pinched wire, etc) is correct. I contacted Lippert and they have authorized the Dealership to diagnose the problem. Thank you.

Hi 07HD, Thanks for replying. No such thing as a silly question. I ask enough of them myself. I checked the fuse (#84) in the engine compartment and it's good. I have an appointment at the Chevrolet Dealer and they'll be doing a diagnostics check to hopefully pinpoint the problem. Thank You !

Another JR, Thanks for your suggestion. I've tried that to no avail. I have an appointment with the Chevrolet Dealership on Monday Dec 20th. They are going to run a diagnostic check to try and locate the problem. Thank you !

Hi Everyone, About the Factory installed Chevrolet Brake Controller in my 2021 Silverado 2500HD, Crew Cab, Duramax Diesel, Max Tow Package ..... I was burnishing/breaking in the Brakes on my Travel Trailer (Lippert Axle & Brakes ) following the Instructions in the Lippert Owners Manual and the Brake Controller is not working now. I therefore have no Trailer Brakes. When I start the engine I get a message in the DIC that says " Service Trailer Brakes". The Trailer Icon on the Controller just above the - and + buttons should light up in Amber color and does not. When I pinch the Brake Controller the Slide Gauge in the DIC between 0 and 100 % does not show the Blue Line that tells how much pressure I am applying. Any thoughts/comments will be appreciated. Thank You ....

Hi MTU Alum, Just a quick Thank You for replying to my 6.6L Duramax Diesel Cold Start post. Your reply was Spot On and is Much Appreciated. I've owned Chevy Silverados ( gas engines ) for many years and as some would say, I am Loyal to the Brand. This being my 1st Duramax and the Quality of the Build, Fit and Finish, Features, etc., this one is a Keeper !! Best Regards, Tucson Jack

Hello, When I start the Duramax 6.6L engine on cold starts and apply pressure to the brake pedal I can feel an "upward clunk or click" in the brake pedal with my foot. This only happens on cold starts. This is my 1st 2500HD Duramax and I'm just wondering if this is normal. I can not find anything about this in the Owners Manuals. I called the Service Department at the Dealership and was told it has something to do with the Vacuum System ? I didn't really understand what he was saying. I will bring this to their attention when I get the 1st service. The truck has only 550 miles as I've had it for only 10 days. I can't remember if this has been happening since day 1. Thank you .....
