Ram 2500/3500 Truck: 383 hp (286 kW), 404 lb·ft (548 N·m), lets see my 06 is 360/650 from the factory I am running a 373 gear and a 6 speed with tap shift, that extra 28hp is nothing compared to the pure pulling power of 650ftlbs and able to select any gear I want, the newer trucks have 400hp/800ftlbs and that gasser can out run them with a load?? I can see a 1st or 2nd gen dodge or a 01-04 LB7 or even a 7.3 psd, but come on....


Who said anything about a gas engine out towing one of the newer 800ft/lb diesels? Come on... quote one of us. "crickets" However, in the real world test done by Pickuptrucks.com, the gassers were right on their tails. Not enough of a difference to worry about. Why don't these tests ever load the diesels to their max tow ratings like they do the gassers? The results might be embarrassing?

Actually, I'd call it a lot worse. Just as bad as the brand fanatics in talking about the big three truck models.

And its always the same folks. Guess they figure that he who argues last wins.

O.K you guys are right and I'm wrong. I'll just keep passin ya on the 6% grades , just make sure you say in the slow lane.


There you go with your fabrications again. The only reason you'd be passing me is if you're breaking the speed limit or trailer tire speed rating. But thanks for admitting you're wrong.[emoticon]


With a light trailer you will be holding the speed limit. Yes I run 70 plus on the interstate everywhere I go.

A F550 as a tow truck is not working hard.


Wow, talk about ignorance! Hours of idling running the hoist, plenty of city driving, occasional rapid getaways (it's a REPO truck), 75-80MPH highway runs, and the fact it's nearly 12,000lbs (it's an extended cab and a 4x4) WITHOUT anything on the hook...yeah, that engine is working!


First off calling me "ignorant" not knowing a thing about me, not know what I do for a living or drive daily is a little far stretched and to use you word , "Ignorance!" My f350 service truck that is my DD weighs 12,000-12,700 daily. I have had unreal loads on trailers behind it. My tool trailer weighs just south of 10,000# that until recently was hooked to it 75% of the time. We also have a f550 that we use to haul some of our lighter equipment. That's all it does. Friday I hauled a 18,000# excavator on a 7,000# gooseneck to a job 100 miles away from where I picked it up and picked up a 22,500# dozer with the same truck and trailer and ran back up the interstate to a job 50 miles away. It regularly hauls these loads. Two 10,000# skidsteers is on it at least 3 times a week. So yes I will say it again, using a 550 to repo stuff is light weight work.

This will be the last time I post on this silly matter. I know all about your Hemi. Pulling 4-5,000# loads it does a great job but I hate to break the news to you, it will not tow a heavy load with my '05 Cummins. Ask me how I know?

My wife's 2011 Hemi with 6 speed auto hooked to my boat and it will NOT hang with my '05 Cummins...........

where did I say that? I said my 650tq.. if your gas truck were sooo much better why do every hotshotter and rv hauler in the country pull them with a diesel, why because they get better milage, and will out perform in every aspect of towing, period... and I know since I owned a 99 V10, and a 04 6.0 gas, but since you pull light weights stick with your needs But most of us who own the diesel need them to pull our upwards of 15k trailers and heavy pin weights, plus the larger and stronger transmission, axles, brakes, frames,ect....


No, you are not paying attention. For maximum speed on a grade HORSEPOWER is the number that matters. End of story.

And while I am pointing out your fallacies, please explain in detail EXACTLY how the axles, brakes, and frame are stronger on a diesel pickup versus a gas pickup. Be specific.

ATTN: transamz9

http://special-reports.pickuptrucks.com/2010/08/2010-hd-16-percent-hill-climb-test-.html

Please read and take note that the 6.7 ram 2500 with same weight trailer as the gas trucks had a much lower top speed at the top of the SAME HILL with the SAME TRAILER than the chevy 6.0 and ford 6.2 gas engines.

Also note that about halfway up the cummins ram nearly stopped accelerating. The ford and chevy gassers kept accelerating right up to the end of the hill. Had the hill been longer it would have been an even bigger gap for the gassers.

The 2010 6.7 ram has MORE POWER and MORE TORQUE than your 2005.

Yes the ram diesel did run a faster time from a dead stop on the hill due to it's low end torque helping to get it out of the hole. however we don't stop in the middle of hills if we can help it. we mostly approach steep climbs already at highway speed. So the ford and chevy gas trucks can hold speed and accelerate on grade better than the 2010 cummins ram. Since the 2010 has more power than your 2005 the ford and chevy should also be faster up a hill than your 2005.

This is controlled testing with proper instrumentation. Not your feeling of what tows fast.

My truck is not stock so this has nothing to do with it. I don't run 16% grades that are only 800' long. That test just proves take off speed of the gas over the diesel. Do that same test on a 2 mile run like running through the Rockies.

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. [emoticon]


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.

Actually, it proved the take off speed of the diesel was better. The gasoline fueled rigs didn't get to the top faster, just at a higher final speed. If the grade had been long enough the gas trucks may have passed the diesel since they were still accelerating.
