I know what you mean. The first mod I did to my 2007 Chevy 2500HD D/A was change the stock shocks out for Bilstein Heavy Duty shocks. It made a huge difference in ride quality especially with the tires aired to 50 psi front and 45 psi rear when empty. The Bilstein shocks really shine when towing a load. Also, check out dieselplace.com, duramaxdiesels.com or dieseltowingresource.com for more info on our trucks. Good luck and happy trailering...
Sig. TV is my second dually. This one rides better then my 05. I've driven that part of I40, from Asheville to Statesville more times then I'd care to, it's not as bad as parts of I26 from Asheville to Saluda. All that being said, I'm very pleased with the way my truck feels and handles. I did can the OEM General's and put Michelin's on it, maybe that helped some, everything else is stock. In my experience
so far, yes the truck does drive smoother with a 5er hooked up to it, even on those streaches of interstate we just talked about. I run 70 psi in the fronts as stated by info on the door jamp, back tires run at 60 empty and 70 when towing. To me, for a 1 ton DRW truck, the ride is pretty doggone smooth, I'm quite pleased with this truck.

To begin with there is a lot of difference between Max pressure and Cold pressure, I'm assuming cold pressure was meant above.
That's correct. I should have stated it as Cold pressure recommendation.

Also, I don't understand putting only 60psi in the rear. Say you need to run down to the lumber yard and pick up a load. WIth only 60 psi in the rear you will be underflated very quickly per tire manufacturer pressure ratings.
I put 60psi in the rear because that's what GM recommends. If the truck is fully loaded to GAWR(RR) of 8200#, the rear tires will each carry 2050#.

Many look at the door sticker for pressure recommendations but keep in mind these are not for towing under a load.
You are mistaken on this point.
My owners manual states "A vehicle specific Certification/Tire label is found on the rear edge of the driver's door. The label shows the size of your vehicle's original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle."
60psi it is! I could deflate them some when running unloaded, but it rides just fine as it is.

MY 3500HD crew cab dually does ride a lot better then my ext. cab short bed 2500HD did. Long wheel bases do smooth out the ride.
I had to chuckle about that stretch of I-40. I don't care what you are driving or towing, it could knock your fillings out. Is there a reason NC can't fix that road?

LOL!! They leave it that way so they can catch speeders... If you're running 85mph or faster, it seems to ride a little smoother, you're just tagging the top of the bumps!!! I really don't know why they don't do something to it... Lack of funds I guess. There's a section of I95 between Latta, S.C. and Florence, S.C. that's about as bad.
Love my truck. Yea it's a bit rough sometimes, but no worse than my 4x4 Dakota I traded in for it. It's a truck....Mileage...sucks...just got back from E. Washington via Hwy 2. Got 8 mpg pulling the rig, without the toy in it...but again...it's a truck. Not so bad on the flat hwy's though.
Our 2008 Chevy 3500, 1 ton, DRW rides like a Truck! We have owned 5 GM Duramax/Allison Trucks since 2005, 1 2500HD, 3 3500HD's and 1 4500 all have been C/C and 4x4 except the 4500. The Chevy Kodiak 4500 had the best ride, of course it had a Link Air ride suspension and Air ride seats. Out of the 3 3500's the 2008 Chevy has the best ride? Why I don't know it just does. I always run my tires as recomended by GM and its posted on the door jam and I also run the Pressure Pro system. My tires run cool and doesn't heat up because there is less side wall flex. Low pressure tires will heat up more. Tires will not last as long if you run low air pressure! We all sometime forget these HD Trucks are designed to move heavy loads and has to have a heavier supension. We have to have a 1 ton DRW Truck because we tow heavy and have a heavy Pin weight. There is no question a 2500HD will tow our Mobile Suites and we have Disk brakes so there is no problem stopping. But the Pin weight is the problem just to much for the 2500HD. It's the the PIN WEIGHT........ If your towing light weight 5th wheels the 2500HD is a awesome Truck been there and done that. Good Luck on your choice. Save yourself some money and get a Truck that will handle the Pin weight, and keep in mind you will probably trade up to a larger 5th wheel. Good Luck on your choice. GBY...
