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...

Its torque determines the gearing you need to keep the engine in its sweet spot at speed. Its HP determines how much of a load you can move at that speed.
I have been reading the posts for a while, but finally decided to chime in after everyone's reluctance to acknowledge the fact that...
Horsepower and Torque are related!

HP = Torque * RPM/5252 So unless you are revving your engine up above 5200RPMS or racing F1 at 19k RPMS, HP is largely irrelevant. It's the torque that matters. Diesel or Gas your TV makes more torque than HP at the engine speeds we are pulling at, any of us. Given that, a diesel usually has superior figures (500+ vs 300-400).
As to the Diesel vs Gas, if you can afford it go Diesel, but there is nothing wrong with Gas. Cheaper fuel, less smelly, lower maintenance costs, easier to work on, and the list goes on. But Diesel has it's share of pros as well. I don't think there would be much of a debate if the up-front costs were identical.
I used to tow our 3k pop-up for years with my 5.3L 4sp 1500 with 3.73. It towed great, but downshifted to 2nd on the 6% grades. I then moved up to a 7000lb 31ft TT and it was having to downshift to 2nd on the freeway (just the 101 not I-17 here in AZ). I recently upgraded to a 07 Classic 2500 D/A. What a difference! It stays in 4th gear up the grades to Flag and can accelerate if I choose, but I say around 60 for sanity :-)
Good Discussions!
Thanks for the calculator.
Do the math and see who is gonna pull more wgt up the grade @ a higher speed.
But it's all a matter of ones preference. I prefer to pull my pig up the hill without pushing the truck to it's limits. I also want a truck that will give me up to 500K miles before replacing the truck or rebuilding the eng. If one wants to stay in a new truck trading every few years and not wanting to maintain cruise speed up the grades then a gasser would be for them.
Bottom line is everyone has bought the truck they want or could afford. It's just that the gassers will not go up the grades with heavy load like a diesel. If they would the frgt companies would have them.
According to some a gasser with an 18 spd trans should pull 80K as good as a big Cat or Cummins or Detroit.
