Which to Buy Duramax LMM, PSD 6.0l or PSD6.4l
 

Hey everybody...

I need to buy a diesel to haul a 6ton cargo trailer through mountains. I have found three I like.
1. 2006 F350 crew cab 55k miles. This 6.0 has just had the fuel system repaired, new radiator and all hose replaced, he HOS ASY egr cool replaced, thermostat replaced, the DUCT ASY-ENG CHR AIR replaced, new egr, new cooler crank case, new eng oil pan gasket. This is taken from the OASIS report.

2. 2008 F250 regular cab with 44K miles. Nothing on the OASIS report.

3. 2008 2500HD with a LMM and 33k miles. Know no repair history.

All 3 are from dealers and all have been registered as commerical use so I do not think any tuners have been used.

This will be a truck for my business so when it goes down I will not be making any money. I plan on keeping everything stock and driving about 50k a year -all with the trailer. Both the Fords are in by budget and the Chevy is about 5k more.

Which would you recomend and why?

Thanks for your time,
El Padrino

The Chevy if you're going to leave it stock, the 6.0 is a no go due to what the Oasis report brought up in my eyes, the 6.4 would be the best I think if you threw a tuner and exhaust and egr delete at it, but stock I'd go with the chevy because of the better mileage and less known issues with emissions equipment

Yea i would leave the 6.o ford out for sure they are not known for longevity or reliability for that matter with or without a tuner. As for the other two i would probably suggest the GM for what you are looking for.

The LMM is basically problem free. The 6.4 is also a good engine, but some had a few problems. Either the 6.4 or LMM would be good for you.

LMM just because Im biased that way, but if I were rich I would probably buy up a 6.4, they are pretty easy to tune and make sick power with very little mods

Saw a 6.4 the other day dyno 595/1220 fuel only with stock turbos, injectors, and HPFP

I would definitely go with the duramax because they are good and reliable sstraight out of the box.And I also say that from my experience the late model 6.0s are rather reliable(05 and later)I dont know much about the 6.4.

I dont trust any 6.0 in stock form, if I own one it will have all the work done to it. Look at how much has already been replaced on the truck he was looking at......

Definetly the 6.4 it has more pullin power than the other beside the 6.0 ford will get you halfway up the mountain then the turbo will go trust me i had a 6.0 and put 4 turbos in it till i sold it for a cummins...best choice of my life.

I would go with the 6.4 for the pulling power and also you said the fords were in your budget and the chevy was 5k more. so i iwould go with the ford and pocket the 5k for future upgrades and also im not a fan of either but i would pick the ford over the chevy anyday.
