CUMMINS TUBO DIESEL QUESTION ?

I've had two with the 5.9 and haven't had a bit of trouble out of either. The Cummins is a hoss, not as fast empty as the D-max but dominates towing. I just finished towing my SRT home from Boomer in a 24' deck gooseneck enclosed trailer at 80mph. Up and down hills with cruise control on.

Personally I wouldn't buy a 6.7 yet, not all stations have the new ultra low sulfer diesel. Almost no truck stops have it. Running regular low sulfer in the new motor will destroy the emissions stuff. If you plan on towing heavy the stick is the only way to go. Again read up on turbodieselregister.com for info on both motors. You can get to 800 ft torque for less than $1000 on a 5.9.

I see I'm kinda late to chime on this thread, lol. You need to check out the turbo diesel registry, great site, great bunch of people and ton's of information.
My 00 Dodge had the 5.9 inline 6 TD Cummins, great motor currently has 257,000 miles on it and still running 40+psi of boost :D :rock: I did a bunch of work to it as things wore out, only real bad thing was the tranny, I'm on my third. I did an ATS Diesel stage 5 this time and its been great. I was towing my 26' trailer then replaced that with my current 32' that now holds my Harley, SRT-10, displays and whatnot, prob 15k lbs. Great truck, ton's of power and oh so much fun to drive with out the trailer. Loved blowing smoke in everyones windows :p
If you go the mod route, do the injectors(I did KAX motorsports 90LBS but I've seen many guys going the Cummins marine route, a little cheaper and more power) will wake it right up, the Edge juice with attitude, adjustable and allows you to monitor everything, MBRP makes a great exhaust for it and ATS makes some high quality parts.
The Mega Cab is quite roomy,I think you'll be happy with it. I opted for something bigger and did the Kodiak, really nice truck but no where near the power out put of my 3500 Ram.
FYI I've just got home from a cross country trip, just about every truck stop had LSD so that's not a problem, legaly they must have it now, just need to put some additives in it to keep her lubricated, Bio-diesel is awesome, wish I could find here in MD

Low sulfur is reformulated diesel fuel to lower emissions. The EPA mandated it to reduce nitrous oxide (NOx) and particulate matter emissions to the atmosphere. It affects #1 and #2 diesel fuel. The distribution requirements are regional similar to reformulated gasoline. Areas with high populations are going to see low sulfur and ultra low sulfur diesel fuel only. There isn’t much you will be able to do to get around using it. Even if you live in a region that doesn’t require it, if you travel you are more than likely going to have to fill up with it somewhere.

Low sulfer is the standard, ULTRA low is the new version that is required in 2008+ diesels. There is a sticker on the pump (usually) that says which one it is. Look in your area and see what most are. I haven't been to a regular gas station lately that didn't have the ultra low. Truck stops are where I still see the regular low sulfer.

I lose a little over 1mpg on ultra low vs the older low sulfer.

Plus #1 and #2 is for summer fuel and blended fuel for winter time to help keep the fuel from gelling. I always forget which is which. I think #1 is the winter stuff:dontknow: . I usually add some additive to help with gelling any way. Sometimes it gets down to -40 below F. And the blended diesel will still gel. The blended is usually a 50/50 mixture of #1 and 2 and I think is rated for -20 F.
