We bought a new 2015 in sept 2014.
Our 2000 7.3 has 130,000 miles and is doing great. It didn't need replacing and we are still using it for non rving jobs.
The trucks are:
2015 F350 Lariat CC/LB DRW 6.7 PSD 4x4 6sp auto 3.73 gvrw 14000
2000 F350 lariat SC/LB DRW 7.3 PSD 4x4 6sp stick 3.73 gvrw 11,200
To say 6.7 has a little more power would be a gross understatement.
We have pulled our gooseneck gross weight of 26.000 lbs with both trucks and the 7.3 handles it very well but I do more down shifting to keep the same speeds and the go pedal spends more time all the way to the floor. The 6.7 rarely needs all of it's power.
The exhaust brake is fantastic. It holds the rig back enough so that I don't need the brakes to hold the speed going down hills.
I like my manual transmissions. I reluctently got an automatic (It's the only transmission offered) and I must say I really like this transmission and the tow haul and exhaust brake.
The comfort is better but the 2000 wasn't uncomfortable.
We haven't had our truck camper on it yet but we have pulled our bumper pull stock trailer with full loads of cattle which is around 10 to 12,000lbs and it's a rocking and rolling surging load and it handled it a little better than the 2000 which handles it very well.
It is all set up for the camper just waiting for a chance to get away.
The price is outragouse but it was on the 2000.
The mileage is very close to the 7.3. around 14 loaded and 18 empty. The regens knock it down a little. ours has Regenerated an average of every 440 miles. It uses about 1gal every thousand miles miles. We haven't gone on any long trips yet and we hope it will do better then. I add it when it is down to half full and it's not that big a deal.
Over all we are very happy with the truck.
