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...

tjcocker - It sounds like you have a nice truck now. But, how much of the difference you feel towing with the new truck vs the old one is because it has a diesel engine and how much is because it is an F250 vs an F150? The F250 is a much more substantial vehicle than the F150 - that's not knocking the F150, just recognizing that the F250 is bigger and heavier than the F150 in almost every respect. Even if the two trucks had exactly the same engine and tranny, you would notice a big difference.
kenoncooch - What you say is true, but I spend a lot of time in the right lane on grades as well and I have a diesel. I know that there are many people who would have you believe that my 3500 CC Dually D/A will pull a 15,000 lb trailer up a 45* grade in OD at 75 mph. The truth is it won't. I have spent a fair amount of time in 4th and even 3rd going up long steep grades pulling my 10,000+ lb 5er. Also, the gassers rev at exactly the same rpm as the diesels at highway speed if they have a tranny with the same (or close) OD ratio behind them. The 1500HD I had with a 6.0l gasser revved at the same rpm as my DMax on the highway. Yes, a gasser will downshift earlier than a diesel, but that doesn't mean that a diesel won't downshift.

LOL...sure the same gear ratios will put out the same RPM but there is NO WAY a gasser of the same displacement (without forced induction) is going to pull anything of substantial size in comparison with the Diesel counterpart unless it's running lower gears.
I have a GMC2500HD duramx and rode with a guy that pulls a simliar size trailer as mine also running a GMC but a gasser. His truck was constantly shifting and struggling to maintain 70MPH on somewhat on flat grades with a small head wind. My truck in the same situation would be in overdrive with cruise control and getting 5 to 6 more MPG. Can you imagine what would happen if it was running the same gear ratio of my diesel? The Diesel's can pull the taller gear ratio because they have the torque that simply isn't there with a gasser hence the better mileage, less shifts, etc...
Obviously everything has pro's and con's but if you do any decent amount of towing with a large trailer Diesel wins on paper everytime.
If you can't deal with the smoke, dirty pumps, noise then get the gasser.
