2015 Tahoe/Suburban 4x4 payload

Both 'half ton' Tahoe and Suburban use the same drive train/suspension and most
other components

Just streeeeeeeeetched a Tahoe to add the extra length

So that lessens the payload because one has more sheetmetal, glass, etc
against similar/same GVWR

On that note, the two Suburban's use the exact same body, but one is a +7K GVWR
while the other is a +8K GVWR with different drive train and suspension

Just curious, I will wait at least a couple of years before doing that. I don't like buying first years of a new generation - there are always some bugs to fix.

On a related note I hate going to dealerships. It's hard to find one that you can trust.

I would start at a dealer lot with something similarly equipped to what you want. I have never met a brochure/web site accurately reflect payload for a model/trim level I was researching. There should be plenty selection of 2015 models at every GM dealer by now.

The Edmunds numbers are fictional, they are "best case" towing options; HD towing package, largest available engine, tallest gears available (3:42 for 'Burb/Tahoe), and no 4WD.

If you are looking at them, the payload is on the door sticker and is based on the RPO options list in the glove box.
