Of course because the Cummins only has 6 connecting rods while the other 2 have 8! On top of that, your mighty Cummins you speak of is always the last in performance so what good does those 6 larger connecting rods do? Hold it back and using the most fuel per mile trying to move the extra un-needed weight? The other 2 have not had any issues with their "smaller" sized eight connecting rods!
Turn up the power on the two 8's and you will need new connecting rods.
Turn up the power to the levels that require stronger rods on the V8s and the Cummins block needs to be longitudinally reinforced to prevent twisting.
The Cummins will be still pulling the grades when the other two are in the scrap pile.
Your weak opinion, and no facts to back it up. However, that could easily be any of the big three, history shows that a GM, or a Ford chassis will do it longer.
How many people do you know that drop anything into another brand other than Cummins.
Look around. People repower all sorts of things with a Duramax. I even seen a Ford Mustang with a Duramax.
Big market for Cummins in Ford.
I don't need the fastest up the hill just the one that will do it the longest.
You have mentioned the Cummins as having the biggest connecting rod, so if we are not worried about raising power levels then why is connecting rod size such an issue? I have noticed there are aftermarket programmers for the Cummins, so apparently there are people who are unsatisfied with being last.
It will go down the grades 28K combined load without touching the brakes.
So will the GM, and Ford trucks with the factory installed engine brake.
Go th the Campgrounds that have a lot of full timers, mostly Ram's a lot of GM's and few Fords. Same with hotshotters and RV haulers.
Out on the highway where real work is being done I see a regular mix of all three manufacturers.
Bottom line be happy with what you have, if not get something else!
And if not create a post like this one to blast the two brands that you didn't buy.
Oh yea, if you buy a F650-750 it won't have a Ford engine but it may have a Cummins 6.7.
Because an F650/750 is so well suited to every RVer's needs.
You look like a fool when you make these sorts of posts. In half the production time as the Cummins the pre-DPF Duramax has proven to be as reliable as the 5.9L Cummins. Lots of Duramax trucks making it to the million mile mark, thedieselplace.com is full of examples. Post DPF the Duramax has proven to give its users less trouble than the 6.7L Cummins. We shall see on the 6.7L Ford.
