Just a little update to dispel rumors from reality etc :-laf
One year ago we put a new Dmax into our fleet of Dodges (99,03,04,04. 5,05) . It now has 45000miles accumulated and has had ZERO issues except for a leaking heater core, that was replaced under warranty and caused by duct work rubbing on one of the tubes. Not one CEL for any reason and DEF use rate of approx 5 usg to 4000miles.
About 2 months ago I had to do a highway run(truck only) with my personal (sig truck). Cruise set at 74mph, Tonneau cover, 1000lbs in bed returned 18. 52 hand calc USMPG. Total of 830 miles in one long day. This speed not the best for economy but time was of the essence.
Last week had to make the same trip and I took the Dmax. Same speed, same conditions more or less. It returned 18. 23 USMPG and rpm was approx 400 less for given speed compared to my NV5600. I might add that the overhead is DEAD on in this truck !
I am begrudgingly impressed and did not admit to my son (his truck):-laf. I told him that I would not be officially impressed until I saw 300,000 on his odometer, and will be monitoring progress
I have not driven a 4th gen except for test drives at purchase time of the Dmax. I am hoping the 2013 Rams will be back up in mileage with change to DEF.
We will be doing a 3000 mile trip this winter with 12000 and 14000lb 5th wheels ,so that will be an interesting comparison.
The Dmax runs pretty much the same towing mileage as all lthe other Dodges when hooked to the ERS trailers . 12US in summer and 10US in winter.
