I'm looking at going from a 2500HD 6.0 to the baby diesel. Can you tell me what the door sticker says for payload capacity? Thx

He did say the towing numbers were @ 75MPH. Might be better @ 60 - 65
I can tell you that it has a 10 speed tranny. You cant feel it shift hardly at all. It does not indicated what gear it is in other than drive. When you put it in tow haul mode maybe it only shifts into 6th or 7th? Might be part of the reason MPG drops so much when towing my inline 4 place. To be fair I've only towed the that trailer twice any distance and was rather windy one of the times when towing. I used to pull this same trailer with an 05 suburban 1/2 ton with a 5.3 in it and got about 6MPG when towing and 70 was about it without keeping it floored, so quite happy with the baby diesel so far.
I also have a 17 3/4 ton Duramax that i tow this trailer with most of the time not fair to compare the two trucks but I average 18-19mpg with my 3/4 ton not towing and 12-14 mpg towing. Reason I got the 1/2 ton was to use as a daily driver and still be able to tow better than the 5.3 Gas in the 1/2 tons and not lose the MPG with the 6.2L. The 3/4 ton for my daily driver rides like crap because its usually empty. Load it up whole different story actually rides pretty good then and can't beat it for towing. 80 Miles an hour and can still pass people if I need to.
Oil change takes 7quarts not 10 quarts like the 6.6 Duramax so little bit of savings there. They both use the same fuel filter, very easy to change on either of them and unfortunately both have DEF. Although I have not had any issues yet with DEF I have heard some horror stories and have a neighbor who has a 17 Duramax that kept running the DEF cycle every 300 miles until they figured out that some sensor was screwed up. I go about 6K miles on the 1/2 ton before it starts warning me to add DEF and about 5K on the 3/4 ton before it warns me. In 2020 GM finally figured out to put the DEF filler next to the fuel filler and not against the fire wall under the hood. So that is a bonus.
Found 2 door stickers with weight listed for the 1500 Duramax
GVWR 7200LB GAWR FRT 3800 LB GAWR RR 3800 LB
Other sticker says Vehicle and trailer must not exceed any of these values
GVWR 7200LBS
GCWR 15000LBS
RGAWR 3800 LBS
Curb Weight 5403 LBS
Max Payload 1797 LBS
9200 LB Tow Rating with a bumper pull trailer and 7100 LBS with a Goose Neck
