We opted for the lifetime oil changes when we bought the truck so maintenance isn't that bad (while we're near our basecamp anyway). I'll never buy another gas engine. YMMV of course.

It doesn't have glow plugs? How does it preheat the cylinders in cold weather?

Diesel's are made for towing. No tractor trailer truck has a gas engine. Simply put the power, longevity and low maintence of a diesel is why anything that WORKS for a living is powered by diesel. The Cummins engine is found in TT units, package trucks, buses. Anyone that has driven a gas powered motorhome and then drives a diesel knows the major difference in how the two engines work. Gas needs RMP's to make power, Diesel works low and slow. It is not always about the $$$ don't expect to get the $$ back by saving on fuel or maintence, but enjoy the miles of worry free towing. I have had both gas and diesel tow vehicles for everything from snowmobile trailer(2k), equipment trailer(10k+), horse trailers (10k live weight) and of course travel trailers (flying cloud 25). Diesel is the way to go to set the cruise at 62mph and let it ride, hills are no issue. And the fun thing about a diesel is the hotter the temp outside the better the fuel milage.

No glow plugs. Turn the key and it starts. Like a gas engine. How? .....I do not know. I expect the ECCU lets in inject for starting. In the teens is as low a temperature as I have driven it in. Had a diesel with glow plugs once. Ancient history. It was a 1988 model. The glow plugs were a real pain and when they swell when they fail you have to pull the head to replace them. Not any more.

The Cummins engine has a electric heating grid where the intake is mounted to the head this pre-heats the air entering the combustion chamber.

That mileage is fair.....my Dodge/Cummins is a 2003, 5.9 with the manual 6 speed 3:73 rear end. I pull a 2001 30' Excella, we travel every summer for 2 to three months.
This year, our trip was 5,800 miles, fuel mileage average was 17.4. That includes towing and local driving after we're set up in the campground.
Towing only mileage was 15.3...

I'm not a mechanic but this is what I've been told.

My 1997 and 2005 5.9L both use preheat grid heaters in the air horn just above the manifold plate. Each has a relay to run the heater. During cold starts a wait to start or indicator light comes on. Key in RUN position, you wait till the light goes off and then crank. Engine starts. The grid heaters may cycle for a few minutes during real cold starts. Starting procedures are detailed in the owners manual.

One more won't hurt. Is a Dodge Cummins a good tow vehicle? Do bees buzz? I much prefer the pre DEF engines and bought a daily driver to save mine for as long as I can. It is an '04.5. She is loaded but has the six speed manual transmission. I like it that way. This will probably be my last Dodge though since the unions have taken over and obola has propped them up so my next truck will be a Ford before the new CAFE crap kills the full size pickup completely. That one should do me until I die.

I've crossed the scales with the gooseneck loaded with steel and equipment as high as 29,500 lbs and pulled that over 600 miles. Not something I'd like to do every day though. My son just pulled a three axle cargo van 2,600 miles from the North Carolina to Idaho and his rig hit the scales at 28,300 lbs. His truck is an '02 I think. Both trucks are four wheel drive straight axles. You can't get those anymore.

The AS is not even there as far as the Dodge is concerned. As someone said, the brakes are big enough to cover some of the trailer if it does not swap ends with you.

The truck is big, heavy and expensive and expensive to maintain. A new one is about 60 grand. Right now, at 137,000 miles it needs a new $680 steering box after about $500 worth of front end work just for parts. You don't need it to tow most AS. I use it because I have it and I like it.

I put Spintech hubs on the front when my unit bearings had to be replaced. Picked up a little over a MPG. No chip and she does 21 city and 18 to 19 highway, 15 to 16 towing the gooseneck flatbed and stock trailer and about 16 or so with the Airstream. I run about 65 to 70 most of the time but 75 unloaded almost always.

Mine went 135,000ish to front end rebuild. Replaced the factory unit bearings with Spintech lockouts that use real roller bearings. Now have to do the steering box since it has some play in it. Will use a Borgman and not the Mopar.

So far upper and lower ball joints, track bar bushings, front wheel bearings and added lockouts.

Have not had the warranty recall check done. I guess they replace one tie rod end?

The is a heater in the intake manifold that heats the air before it goes into the combustion chamber. A lot more effiecient and effective than glow plugs..

I have made the decision to keep my '08, do the appropriate repairs, as needed. While there are some nice features on the new trucks, for $40,000 to trade, I can do a lot of custom work on mine and have my "cockpit" highly personalized and all the goodies I could ever need.

As i travel alone to visit friends around the country, I like to have all my driving tools at hand, primarily to assist in maintaining alertness. To do this on a new 2015 would be a lot of work. Also, on a newer truck I would have to put up with the 20,000 to 30,000 mile break in period.

While I do like the DEF system in principle, hopefully someone will come up with a more efficient emissions system, giving the power of the old emission control free engines, yet providing some reduction in harmful stuff from the tailpipe.

Mine is 2wd and w/o the steer problems. But I've read there is a new MOPAR box. Worth checking. And consult with Denis 4x4

My only comment to the above is the newer engines, even with all the emissions,have more power and torque than any of the older ones, they even last longer. The 1992 dodge only had around 160 hp the 2007 is near 350 hp all done with computer technology....the automatic transmissions are also so much better..
