We don't tow a small little trailer and shower in hotels. We tow a 30ft 5th wheel and stay in various campgrounds. We're also very happy with our truck's performance. We keep up with traffic. Sorry if that peaces you off. :B

Doesent p me off at all. I'm happy you are satisfied with your rig and enjoying it. I just take issue with the info you put out about a gasser being a better tow vehicle than a diesel. I don't care how much you preach this, it's just not true in the real world.

Please quote anywhere that I said "a gasser is a better tow vehicle than a diesel". The only issue you seem to have is telling the truth. My Hemi Ram towed the same 10k lb 5th wheel faster up the grades than my '03 duplicate SO 250hp Cummins Ram. That's a fact. I never said the Hemi was a "better tow vehicle". 345 hp will tow faster than 250hp no matter what fuel it burns. That you can quote me on. We tow in the real world. Not sure where you're coming from.

I'm coming from a part of the country that has real mtns and extreem heat. Not sure what % grades or how long they are where you are but I'll bet my truck against a doughnut You can't tow with me in the mtns here. With your 10K trailer And my 13K trailer. my truck wweighs 8200# also. I'm not sure you undrstand what a real pull is.

Ok, and here's my challenge to you. Quote anywhere that I've ever said my truck or previous Hemi powered 2500HD Ram would out tow a modded or newer HO diesel in the Rockies. I've said many times over the years that if we towed heavy in the Rockies, I would have another diesel. A HO Cummins Ram. I have only stated many times perfectly clear that my Hemi Ram would out tow "MY" SO Cummins Rams towing the same 10k lb 5th wheel. Monteagle is our only 5~mile long 5-6% interstate grade to deal with. The 5.4L tows a lighter 8500~lb mid profile 5th wheel about the same. "MY" Cummins Rams had trouble with only 160-250 hp. Any engine gas, diesel, ethanol, steem, pedal power or turbine with the most HP will through gear reduction, torque multiplication, make the most torque at the output of the transmission. Flywheel torque doesn't mean squat if you can't rev it enough to put it to the ground. Torque alone is a static measurement. Has nothing to do with speed. Only with rpm does it equate to speed. The two components together are known as horsepower.

I think this guy is one of the few that actually has a true understanding of what the Torque rating of an engine is. He stated a very specific situation where the higher peak POWER (hp) of the gas engine gives and advantage over a "similar" diesel.

Of course some people had to get completely offended that there could be ANYTHING a gas motor could do better than their more costly diesels. Well, there is... max operating RPM. If those diesel engines could acheive 6-7k RPM, then the total power potential of those engines would blow the gas away.

Guess what, on a long pull up a high grade, the diesel will blow the gas away at first. All that torque will get the wheels spinning much faster. Then, as the speeds increase, we get out of the range of torque and into max power or HP. The diesel has done what it does best and powered that heavy load up but it has run out of steam so to speak. Once it reaches its max power, you aren't getting any more out of it. The gas engine in Hannibel's specific example has more power to give and will keep accelerating beyond the diesel. That's just the way it is.

I know that diesel is the better option for towing heavy loads. I also know that peak power is peak power. It's pretty rare that that would come in to play in many real world settings but it is what it is.

Rememebr the old (80s) Chevy small block gas engines in the pickups that had alot of torque (For the day) but not much HP? It was the same thing. They could knock you in the seat of your pants pulling away from a stoplight but started gasping when passing on the highway.
