Never gone that low. Unladened, my rears are at 50 psi and 85 when I load her up.

These days I tow about 60% of the mileage put on the truck. I tow at 75 psi rear and front. Even though I air down when not towing for a few weeks the rear tires are still worn more in the centers than the outside. The fronts are very even. I don't rotate with the aluminum wheels and have about 40K on these and plan on another 6-8K more miles. I'm sure the air-down cost some fuel mileage but it is well worth it to me for the ride.

I've not too often seen where someone goes from a DRW to SRW when towing like heavy loads

I love my dually. The stability and braking is great when towing my 40' fifth wheel. I Never thought about adjusting tire pressures when towing. I just keep mine at the factory recommended pressure that is on the door placard. 70 psi front and 65 psi rears. Those pressures should be good up to max gross vehicle weight right or should I be adjusting the pressures when towing?

Keeping them as per the door placard is fine, and I believe correct for doing max-towing.

But many people find the truck rides very stiff when unloaded, so they will reduce the tire pressure to 50 psi or so and drive around empty like that. When they want to tow again, they air up to the placard [my '04 Sierra 3500 wants 80 psi rears I believe].

Got my new truck!

Sealed the deal today. I am the proud owner of a 2016 Onyx Black Denali 3500 DRW. I love this truck, just drop-dead gorgeous. I spent a while tonight in the garage just looking at it.

Thanks for the guidance.

The door placard is posted in terms of max load for liability reasons. Running 80 psi in an unloaded dually is not only unnecessary, but will result in uneven tire wear. Like Tired Farmer, I run mine at 50 psi unloaded and run them up to 80 when the 5th wheel in on the back. Technically, even with the 5th wheel, I'm over inflated for the weight, but I run them at 80 to counter act the additional pressure of hitting pot holes on our sorry infrastructure some refer to as roads.

Congratulations, that's really nice... What options does she have? The front end and big grill look awesome....Good luck and enjoy it..Mine is also a daily driver and I love driving it.
Back in 2012 when I was shopping for my dually I really like the look of the GMC. The big front grill gave it a nice truck look. The only thing I didn't like, which might sound petty, was back in 12' the headlights were rectangle and the fog light/driving lights on the GMC were round. To me it just didn't look right. It threw the appearance of the front end off, to have rectangle head lights and round fog lights. So I went with the Silverado. Plus I liked the hood with the 2 black louvered grills and the Duramax Allison badges.
