I,m towing with a 1999 Ford 7.3 SD crew cab long bed. It's naked, no chips. This is a beast and, like the last post, seem to pick up power the faster I go. There is one problem, though. It has a natural drift to the right when ever I am passing a Sears Craftsmen store...

With a Duramax/ Allison, is the tow haul mode button required. Do I haul in overdrive, tow/haul or what? My 5er is only 6000 lbs dry.

i don't know what it is about that pull to the right at that exact location ... but you will often see my big ol' parked at the very last row in the Sears lot on Saturday afternoons. Apparently about 30-45 minutes later, it runs smooth as silk on the way home.

Beauregard,
Welcome to iRV2. You sidestepped the "New Member Checkin" area and leaped right into the good ol' truck discussion. Glad to see you around,
Mike

I tow with a 1991 Ford diesel powered ambulance type III (Huge box) made by PL Custom. Yes everything still works lights, siren etc

Hence the license plate frame on the trailer "I'm not weird I am gifted"

Maybe you don't consider my 31 foot, 11,000 lb. GVWR TT "serious towing", but I take it seriously. I chose to have a big block gasoline/Allison combination in my Chevy HD because it has plenty of power, is much quieter than the Duramax, I don't have to deal with the fuel stench and I did the math on the fuel economy vs. the diesel option cost.

If I pulled 6 to 8 percent grades frequently or put more than 20,000 miles a year on the truck, the calculations might have come out differently. My last RV was a motorhome that was heavier, had less power and my experience was still that I was most often stuck behind overloaded eighteen wheelers that couldn't/wouldn't maintain speed up grades.

So with a gasser and Allison combo,there would be a huge saving(not buying the Duramax)but I guess the power wouldn't be as much? I don't want to be under powered,and want the best milage possible. I don't drive all that many miles so a Duramax may be overkill..?

The big 8.1 allison can haul the mail but gets poor gas milage. The D/A gets about twice the milage pulling and at least a third more empty. You can debate forever on diesel vs gas. The d/a is one mighty combo and you'll see many in any campground. Loud ..no, smelly..no. An increadible pulling machine...yes. If you have mountains to get over it's gonna save you time and money and make for a very safe tow.

Thanks Paul, you answered my questions. I thought the gas/allison may be a hog.

Brad you asked about the t/h in the D/A combo. No it isn't required but I highly recommend using it. What it does is hold the upshift points longer to help get the load moving (not as important with a lighter load). Also locks up the torque converter so there is no heat buildup in the allison from slippage. Also it helps slow the load and save your service brakes by downshifting when the brakes are tapped. This works in traffic very well and it also works on steep hills in conjuction with the allisons grade braking feature, holding back the load at a managable speed (remember a diesel spins freely when you lift the acceslerator..no backpressure like a gas engine). I would not tow without using t/h mode. If you have a tranny with a computer that smart why wouldn't you use it? A GM service manager told me the allison is a very simple device mechanically...the only thing complex is the computer and most issues are fixed with a re-flash.

My Freightliner is the same width as dually pickup, but is three inches shorter than my old Ford crew cab long bed. Parking is easier due to the 55-degree front wheel cut and added visibility. With the Freightliner I can simply pull in and out of a parking spot without having to jockey back and forth.
One of the best things I like is the visibility for the driver and passenger. Visibility and driver comfort was a primary concern when they designed this truck's interior.
Negatives:
When bobtailing it does not ride as smooth as the Ford, and the height of 9' 8" keeps you out of fast food drive thru's. Well, . . . . maybe the later is an advantage?

Unfortunately, you have the mileage stuff backwards. Because the gas engine is running under heavy load when towing (and therefore at its most efficient), the mileage difference between gas & diesel in the same truck gets down to the energy content in the fuel (roughly 10% advantage to diesel) and combustion efficiency due to compression ratio (again about 10% total advantage to diesel). However, running unloaded, the gas engine is very innefficient since it has to be throttled back so much most of the time while the diesel always runs unthrottled.

My truck gets about 9 mpg towing and about 12 mpg not towing. I've driven Duramax trucks identical to mine before I retired and the best mileage I ever got in mixed urban driving (not towing) was 17.5 mpg, so I really doubt anyone can get 18 mpg towing my trailer with one.

Noise is subjective, I'll agree and leave it at that. So is how the exhaust smells on the newer generations of diesel engines. What isn't subjective, however, is the nastiness of dealing with diesel fuel and its stench. Maybe you guys get used to it, but I never have and I used to have to routinely fuel company cars (Cadillacs) with the stuff.

But the bottom line is if it made economic sense or a diesel engine did something that my gas engine doesn't for me, I would deal with things I didn't like about diesel engines, but that isn't the case.
