I have the 2500HD and the sticker on the door says 55 front and 80 rear. I too asked a lot of folks what pressure to run. Most said to lessen the rear pressure. I settled with 55 front and 55 rear when not on a camping trip. While on the trip it is 55/80. I have found the truck rides well with this pressure and have had no problems.
Empty truck tire pressure is kind of whatever trips your trigger kind of thing, but remember that tire mfgrs state both a max. and min. tire pressure. Load range E tires have a min. pressure of 50psi and max of 80psi set by the mfgr. and other load ranges have their unique limits. Numerous factors are used by the mfgr to establish these pressure limits.
I agree with what you said about cummins bolts to a dodge. Two bad chev or ford does'nt smarten up a bolt down a cummins. I had a 94 dodge with cummins, good motor, crappy truck !
Be careful when you go by the door pressures. Looking at the sidewall will give you the correct max pressure at the max load rating at cold temperatures. The tire manufacturers know best and thats why I go by their recomendations.

Generally, if your sidewall states 80 psi max at a maximum load capacity, thats what they mean, no ifs ans or butts. If run your truck unloaded, lower it to 70 psi, your truck will ride a little smoother and your wife won't nag you for the bumpy ride.I saw a fellow 5ers tires last weekend, worn down, I wouldnt use those on my truck. I thing that because tires is my business, I pay more attention than the ordinary guy. The most important thing to do with tires is rotate every 10,000 km for even tread wear.
Well everyone certainly has an opinion about tire pressure. For what it's worth, the door on my 97 Dodge diesel says 65 front 80 rear (LT245/75R16-E). I run 65 front and 75 rear when towing a 5er with 2300 lbs of hitch weight, 45 all the way around empty and I've seen no adverse tire wear. The 4x4 rides real rough if tire pressures aren't lowered some. Tire gurus may think this is ridiculous and dangerous to buck the mfg's recommendations, but this works for me.

Hangman, I have a curious question for you. I have a Canadian friend and he mentioned that a truck warrenty in Canada is 100,000 KM vs 100,000 miles in the US. You mentioned to rotate at 10,000 km which would be vs 10,000 miles in the US. Kind of strange that the mfg's would do that, although I can believe that is true.
I have a Silverado 2500 with load range E tires. The sticker on the door says 50 front and 80 rear. I felt 80 was too much when not towing so I sent an email to Chevrolet and asked them. They took the CYA position and would not budge from the door sticker regardless of driving solo or towing.
Personally, I rotate every 10,000 km which equals 6,000 miles. The tire wear is evened out, so when its time to replace, they are all ready for the dumpster. For me that is every second oil change which is easy to remember.
