If I could find a cherry older truck I might consider it. But when I'm trading in a truck that's been rode hard and has a crooked number leading the 6-digit odometer reading moving into a new one is nice. The warranty is a plus too. I recently retired an '83 because it was getting to where I was spending 1/2 of what it was worth each year just to keep it on the road. Nice looking still with a fresh interior and paint, but can't justify a reman engine and transmission now not knowing what will fail next...

Now I know you don't mean going back into the 80's for a diesel (some were real pigs), but I don't want to buy someone else's '90's or '00's headache either. I read of many people bombing their 7.3's with propane injection, wild chips, and who knows what else. I'd hate to get one of those without knowing it.

I appreciated the banter as well. I don't have anything against diesels. But I have little experience with the ones they put under the hoods of vehicles. Most of the ones I've dealt with were much larger. The most impressive was a MAN unit I tested in Augsburg, Germany. It idled at 1500rpm and made 10,000 hp at 1500rpm. The smoke from the stack blotted out the sun when we threw the load on the generator. That thing would take a 3,400hp instantaneous load without dropping more than 1hz. Would have taken more except the turbo (about the size of a 55gal drum) was too heavy to spool up any faster. While I was there I saw where Rudolf tested his first diesel, neat.

Most of the big engines we deal with have spark plugs and drive compressors. Fuel cost pretty much eliminates considering anything else. They get their fuel from the natural gas stream they are compressing. Of course for the big power demand we burn natural gas (sometimes stabilized crude) in big turbines. Anywhere from 5,000hp to GE Frame 9's that make close to 120MW (140,000 HP). The saying here is, "If it spins, it wins."

I know lots that have granaded them. Everything has a limit. I got lucky an older gentleman in his 80's had mine along with every maint record. 100K and spotless which it still is. I have only put 51K on it in 8 yrs. It's only used to tow the toyhauler and an occasional trip to Home Depot. With those #'s it will last longer that I will being almost 64 myself. I still say it tows better and will run longer than a gasser. But I respect others choices. The sparring is fun and think how much info we have extracted from this arguement. Bottom line is if I were going to buy a new one, I would downsize the trailer considerably and go with a gasser due to the extravigant cost of a new diesel truck with issues. And all 3 have issues that I don't want to deal with.

Maybe I'll get a Prius and stay in a hotel.

I'll probably be buying a F-350 or GM 3500 SRW diesel 4x4 in the Fall next year. Reading up on them it seems GM has issues with DEF and Ford with water in the fuel.


Please keep in mind that BOTH are using the exact same high pressure fuel pump, the Bosch CP 4.2.

Thanks, so the fuel pump isn't going to influence the decision between the two.

Does GM do a better job of conditioning the fuel before it gets to the pump? I see water in fuel issues with Ford, but not GM.

Sport45:

that is unknown to me. I do believe both use two filters, one frame and one engine mounted. As far as one being more efficient/better than the other, I think they're both about the same effectiveness.

Interesting that Ford just announced changes to the Powerstroke for 2015, some of which included a NEW high pressure fuel pump. So, perhaps the reports of trouble with the current CP 4.2 pump are causing a change. But to what, I don't know. I mean, to my knowledge there are not many choices out there to build such a pump besides Bosch and Siemens. And I don't think Siemens has anything like the current pump by Bosch. But, just a silly guess on my part.

I disagree. Nobody "needs" diesel. Some just want it, can afford it, and like it. Gas engines will get you anywhere a diesel can.

My next truck will be a diesel 4x4 without a doubt. But not because I "need" it. I'm just at a place in my life now (kids out of college, nearing retirement, etc.) that I can afford to pamper myself a bit.

If I don't like the diesel I'll go back to gas. That decision will be made in the next few years.

If somebody was to put a ~5 liter turbocharged gasoline engine in a 1-ton for significantly less upgrade price than the diesel that is probably the way I'd go. With a modest 8 psi of boost it would act like a 7.5 liter at sea level even on the higest mountain pass. It wouldn't get the miles per gallon of a diesel, but the cost per mile would be close enough for me.


So if you were full timing and towing 18-20,000# through the mountains you would still go with the high revving turbo gasser?


I'll take an F-550 with the 30-valve V10 for that weight.

I wish that they would offer small turbo or super chargers on gas engines in HD trucks. For high altitude mainly of course. Gas engines already have way more power liter for liter than diesel.


It's not power that matters when towing, it's torque, and there is nothing that even comes close to the torque/liter of a good TDI engine. The Bluetec for example gets 455ft-lbs out of 3L, and when it's not towing, also gets 30mpg on the highway. You can't even come close to that with a gasser. Yes, a gas engine would have more power, the same bluetec "only" gets 240hp, but it's plenty for passing at 80+ without a trailer, and of course, it's never safe to go above 65 towing anyways. You can also add that diesels run cooler, at lower rpms, and tend to last significantly longer.


No, it's power. It's very simple: one horsepower equals on horsepower! It really is that simple!

Wow... I cannot believe that this thread is still ongoing...been through 3 different trailers since I first posted on it..LOL.

Well all I can add at this time is that now, at 250,000 miles, many a gasser would be sitting by the wayside...and I can say with good certainty, my truck will still be pulling whatever trailer I have well into the future. $ for $, and if you can afford the up front cost & know your way around a set of metric wrenches, diesel is the way to go - handsdown.

The one thing I would really like to see in our country and province in particular is a set of regulations ensuring that those that pull, are pulling with a vehicle designed to pull said trailer and have the proper hitching system installed and in use.

Too often on the Highways of Alberta and BC I see a Front Wheel drive SUV pulling a ~23+ trailer and even though it may be set up with a Class IV hitch, the thing is usually weighed down by passengers (wife+kids) 4 bikes on the back and to me looks like an accident waiting to happen.

my $ .02 at this stage of the thread. I'll be back....

I watched a gasser go lots of miles in one of the toughest applications out there: an F-550 repo truck. Engine was replaced with 553,000 miles.

Should we start a petition to ask Obama to make gasoline illegal by executive order?

If you own a gasser you are destined to a life of driving in the slow lane, the solvent properies of the fuel make the oil useless, your vehicle will burst into flames in an accident, and your babies will be born nekkid. [emoticon]


No but he could get the price down a little. LOL. I'm not bashin gassers just makin a point. Like I said in a previous post everyone has different wants & needs. If a gasser meets your needs and that's what you want by all means buy one. We have a guy that camps with us drivin a 3/4 T Chev with a 454 towing a 5er. WOW is he late getting to camp. But it's what he has and obviously it works for him. Some buy new every few years I choose to keep it forever. This thread has brought out lots of info, heat, and a little humor along the way. I enjoying the sparring. At the end of the day I just hope everyone tows safely and has a good time doing it in whatever vehicle you choose. Y'all have a good night. I'll be back tomorrow for another round.


A 454? So the truck is, what...15 years old? SERIOUSLY?!?! That's like saying diesels are slow because you compared a 30-valve V10 to my 7.3 IDI F-350!

Bosch sold Ford and GM a bill of goods. GM is stepping up and fixing them. Ford is reaming their customers. It is that simple.
