my 7.3 excursion is a dog but 250k and not one problem. this is my 4th 7.3 and other than cam sensor's have never done anything but change the oil and they all were 200k + and not even a cam sensor in this one. will never be able to justify the jump to a common rail. ever.

95% of the research I have done on the injector failures is that they are LEAKING, not failing at the coil/magnet. Some suggest due to dirt clogging the injector, others suggest varnish build up from cheap fuels, then others suggest water in the fuel acting like a water jet cutter destroying the injector tip, and others say they just wear out due to lack of lubricity in post 2007 fuels. ALL of those factors can be eliminated pretty easily.
I have a 3500 with a 5.9 and 125k miles, and 2500 with a 6.7 and 70k miles with a lot of deletes. I am going to swap injectors on the 5.9 and keep putting 2 cycle oil and injector cleaner in every tank. It's a gamble but I think a reasonable one. The 6.7 is just going to keep getting 2 cycle oil and injector cleaner for now. Both trucks have tuners and run great....I just wish the 6.7 had the NV5600 like our 3500 instead of the G56. I daily the 6.7 2500 and it's fine with a nice light clutch. I just can't put any power to it or it slips BAD. That will be fixed with a twin disc and back on with the 100hp tune.

You towed 13k with a 1500? That is crazy. I had around 6.5K (toy hauler) behind my 1500 long bed with a 5.3 just the other day and it was probably at or very near the limit for that truck. It will run down the flat road at 70-75, but it stayed in 4th gear most of the time and it got 7mpg.

Have a buddy that is going to TRY and tow a 26' enclosed aluminum trailer that is decked out with a Tundra. I've told him several times now that he should start shopping for a 3/4 ton at minimum. He gets the trailer in a couple weeks. I can't wait to hear his report! LOL! Hell, my 3/4 ton with the 3.42 gears can be a dog when really loaded. I am thinking of getting 3.92's or whatever the next set of gears are. Ever since they started using AAC axles instead of the Dana's, I have lost touch with details on them. I also need to go down in tire size as this truck came with a +1 tire that is about 1.5" taller than stock.
eh, first world problems I guess! LOL!

You might think you want a 12v until you drive one... they just don't compare to a 6.4 or 6.7 V8 IMO
I like the power my 6.4 makes no doubt, it is just when it breaks. I'm about to hit 500 miles on this 6.7 and I can honestly say it is the best all around diesel truck I've ever been in. Quite, economical, powerful, etc. I don't know what they changed but it rides way better than my 6.4, its also much more quite in cabin, not just engine noise, but wind/road noise. I'm seriously thinking about leaving it 100% stock, which would be a first with any vehicle for me.

Don't put a 5r behind a Cummins IMO. it won't hold the low rpm torque, and you'll spend forever getting the stand alone controller dialed in...
I would go built dodge 4sp or wiggle stick. But really though, I wouldn't swap a Cummins. Total waste of time and money.
Matt, factory AAM ratios are 3.42, 3.73, and 4.10. You should be able to find somebody who will trade axles with you
