Yes, my Dodge 2500 was a Hemi. The tranny was a poor match for that truck. It never towed more than 10,000# which I did for 2 years prior with a F-150. No issues with that truck but had 3.55 gears and just could not handle that weight.
As for the gas diesel thing I agree 100% that for most buyers the gas engine makes since. Well kind of. The diesel will give you on average $5,000 more on trade over a gas. The problem is, and this is not being brand loyal, Ford is the only one with a gas engine up to the task being the V-10. GM really screwed up dropping the 8.1L, it was a sweet engine. Dodge had a good start with the 360 and even the V-10 they had back about 10 years ago then went Hemi crazy. I bought into it because of the funny commercials. The reality is its a great car engine but has no place in a truck.
I do know the 6.0 has some issues but the total package of the 04-07 Ford truck is hands down the best total package for that time period. Dodge had a great engine in the 5.9 but the rest of the truck was a step behind the GM and Ford offerings. GM has issues with the Dmax up till 2005, especially with overheating pulling heavy loads. The real issues I have with the GM products is the chassis, its the worst in the class. They also have know problems with the Allison cooling lines, steering shafts, ect.
One last thing then I will stop. Ford sells over 83% diesels in the 3/4 ton and larger class. Dodge and GM sell in the 40% range. As far as total sales go Ford outsells diesel equipped trucks of both Dodge and GM combined. This alone means there are twice as many Ford diesels on the road compared to both GM and Dodge. So yes, it will look like they may have more issues but that is not the case just by numbers alone.
Again, I am not builder loyal. I would buy a Dodge tomorrow if it was on par as a total package with a Ford in my eyes. I would also love to see Nissian, which I currently own one and think its the best truck I have ever owned hands down, build a diesel. Same goes for Toyota. I would not touch another GM for a few reasons but mainly because of the whole government bail out deal. I have given Dodge and GM a try in the last 6 years and they just let me down and cost me money in the form of lost business due to down time. Fords have done me right. I have owned about a dozen since 1997, of which 3 were diesel, and only 1 night spent in the shop total.
