Dang you two, just accept that year for year a Diesel will out tow a gasser!
I would put each of the big threes, diesels up against their gas engines, no match!
I pull a 11K fiver up 7% grades, and can accelerate to the 55 mph speed limit while doing so, only addition to my 01, is a simple Power Puck 50 hp and about 150 ft. lb. of torque, running 3.55 gears.
If it was gas with those gears it would be doing 35 mph at the top of the hill! I hate to think what it would do with 4.10's!!!
I've run both gas and diesel and both do the job. My question is... if diesel is so much better then gas why do so many diesel owners chip their engines? Even yours must have been lacking that you had to chip it. Sure don't see it as much on the gas side.
7% slopes? Why not a real hill? With my gas engine a 7% is nothing. I do 18 % and there are some who tow hills even steeper and we haven't chipped our engines an extra xxhp and xxx torque.

I have a 2008 Toyota Tundra and a 2012 Dodge 3500. I tow a 27ft toy hauler that weighs 11.5k and tow 470 miles round trip from Scottsdale to Glamis CA 2-3 weekends a month in the winter.
I tow 75-77mph and get 6mpg with my Tundra and at the same speed with my Cummins I get 9mpg. But the Dodge is still new, so that will probably go up a little in the next 5k miles or so. Anyway, thats my .02. I have 3.73's in my Dodge and 4.3's in my Tundra

Just where do you find an 18% grade in Ohio?

I'm sure there are some. Many areas in the Midwest have steep grades. The difference between the Midwest and the mountains is that the steep Midwest grades are shorter in distance.

Contrary to what lots of folks think Ohio is not as flat as a sheet of plywood. Within 8 miles and between my house and favorite camping spot is 18%. I've been on roads with steeper hills in Ohio then any other state including the rocky mountains. They just aren't as long. I've been on steeper hills with my rig but didn't measure the slope so I use the 18% figure to be safe.
Back to Diesel v Gas my question still stands, if diesel is so much better then gas why do so many diesel owners chip their engines?

Simple answer - because they can and not all do. When a cheap box promises 100-200hp and better mileage the temptation is too great for some. Many gas truck owners chip them with far smaller gains. I have not and will not use a tuner. I also prefer the no stink or noise of the stock exhaust - some use a tuner to eliminate the emissions. As stock 365/685 is more than enough for my needs.

I find that chipping diesel motors today is not as common as people think. I know dozens of guys that have diesels and maybe 3-4 have theirs chipped. It would be interesting if there was poll on RV-net that people would respond to honestly indicating the true numbers that are chipped.

Well I chipped mine to "Wake it up" early electronic diesels very conservatively tuned out of the factory. Factory setup on my 01 Cummins was 235 HP and 460 ft. lbs. of torque, I installed about the smallest chip available. It claimed 50 hp and 150 ft. lbs., which it delivered most, so now I have about 285 HP and maybe 600 ft. lbs. of torque, and get 20 mpg HW, 12 towing 11,000# and about 14 - 15 in town. I would not chip a new diesel.

Good point. You also have to take into consideration the new laws and monitoring (electronic) systems on new diesels. With my 99 7.3, in addition to the air filter, tuner, gauges, etc., I had a bigger downpipe and a straight 4" exhaust all the way back. Don't know if you could even do that with the newer diesels.

Because they can. If you could add a nice hp and tq gain for just a few hundred dollars and it only took a few minutes to install, you'd do the same.
I love my big-block gasser but it would be a much better truck with a diesel powerplant.
