Running fine with no noticeable differences on performance or mileage.
Note: I pull a trailer with this truck on average 3-4 days per week with my business.
With the last oil change (every 5k), I had to turn rotors and change front brake pads. Had even wear the whole life of original pads and was surprised to get 68k out of them.... Still have 30% on rears.

One question: the engine should be cold to change plugs, right? I mean as in overnight cold, or just cool enough to not get burned? On my Dakota, I have only changed plugs after sitting all night.

Cold enough to not get burned is all I wait for.

I changed mine at 30,000 and could not in any empirical sense say there was a difference, but I initially thought the transition from 4 to 8 or 8 to 4 cylinder mode was ever so slightly smoother. I detected no difference in idle quality or fuel consumption. Those plugs all measured about a .002 increase in gap, assuming they were installed at spec at the factory. I've talked to others that have gone as much as 80,000 miles on the original plugs and they swear their's were running fine. I'm at 67,000 miles right now (7K over) and it still runs great. I'm thinking I'll leave them in through the winter.
Still on the original pads and rotors. In fact, the front are less than 50% worn, but I don't pull a trailer that often and generally drive more sedately than most. After seven tire rotations I'm having trouble with the wheel lug nut caps becoming crushed or rounded over. I suspect the tire place isn't using the correct size socket. They tell me that the caps swell because the lug nut rusts underneath, yet the one that peeled off shows zero signs of rust.
Best regards,
Dusty

"easy on oil and plugs" ... why yes, my 201,000 mile hemi still has its original plugs (hopefully they will not give me trouble with removal!) In fact i have only changed oil (mobil 1 extended performance every 5k-8k miles), 1 serpentine belt, and an egr valve(so she could pass emissions). I need to do exh. man. gaskets, so i guess ill do the plugs while im at it! Thanx Dodge for another amazing addition to my fleet of mopars!

That Mobil Extended performance in right conditions is a 15,000 mile oil. Standard Mobil 1 is a 8 to 10,000 mile. Oil analysis on Hemis show that are not prone to much fuel dilution or oil shearing. You could run that extended performance oil easily 10 to 12k. Run a quality paper air filter. Just my 02 worth of advise.

That sounds like a bs story about the lug caps. Mine has had same number of rotations and they look new....
