Looking for opinions on the best power reliability I'm general gas motor plowing. Consider all to be high mileage 150k+
For a back up, I wouldn't even let mpg be put into the equation.
This will not be your daily driver, but you will want to drive it on a consistent basis and not let it just rot. That being the case, assume it will only be used for plowing and hauling your trailers. How heavy are your trailers? Would a v10 benefit you? They all have proven track records pushing snow, so I'd look at what else you'll possibly use it for.
IMO, I would just find the best deal, on the best truck, and go with it regardless of the motor. With trucks as old as what you're looking at (I drive one as a daily driver also) you have to just know going into it that you will eventually have to throw money at it. That being said, look at what is involved with engine work (ie ford v10 has to have cab removed to work on a lot of things with the motor).
Like I said though, find a good deal, and don't look back. Make money with it, and send it to pasture when it's life is finished.
I've only plowed in that truck a couple times. It's a F350 1 ton dump with a 9.6 XV2 and compare to my truck (F250 with XLS) just seems to suck down more fuel. I know towing with the 430's are night and day compare to the 373's in my truck.Do you notice any difference in plowing capability with the 430s?
The dump is rarely empty, it's either towing or hauling but towing our trailer around town it gets 6.2-7mpg and the newer F250 gets around 11mpg and when we tow our travel trailer (37ft 9klbs) we get right around 7-8mpgWhat's the fuel mileage empty, do you know?
