Diesel vs gas......................
OK folks, there have been a few to many diesel vs gas threads that have shall we say gone to "Hell and a hand basket"! So if all of you would put in you BEST, no flaming reasons for going gas vs diese...

hindle_az - Your reference to a gasser of the same displacement "without forced induction" struck me as a little misleading. I simply wanted to point out that a gasser will produce far more power per unit of displacement than a diesel without a turbo. And, there are still quite a few gassers in cars that are turbo'd from the factory. If they turbo'd the truck gassers in the factory, the cost would be a lot less than you think. If I add a turbo to a gasser on my own, the cost will be very high but not if it is done at the factory.
As for the tranny shifting, that is a tranny problem, not an engine problem. If the truck couldn't hold the hill in OD, then the tranny should not shift intoo OD. Whether there is a gasser or diesel behind that tranny is irrelavent.
And, no, a diesel will not always hold OD. I came out of Kelowna BC a couple of weeks ago in my 3500 dually D/A and a 10,000 - 11,000 lb 5er on back. Going up a 6 - 8% grade, the best I could do was around 52 mph in 3rd gear. As soon as I crested the grade, the tranny grabbed 4th, but it wouldn't coming up the hill.
Lynn Rupper - Your engine has less power than mine, yet you are able to climb a 6% hill in direct with a heavier trailer than I have? It is possible if the tranny ratios allow it, but mine wouldn't. When my tranny grabbed 4th, the rpm dropped from 3000 to 2400. I don't have the power curve for the LLY in front of me, but I think it develops a max of around 250 HP at that rpm. It would appear that that hill demanded more than 250 HP, so my tranny couldn't upshift.
