Thats a healthy VP cummins...
as for fuel mileage of gas vs diesel, diesel will always win. as for buying a power wagon vs diesel its a little tougher...
the way I look at it is if the OP can afford a diesel and knows about Carli he can afford to build a diesel version of the power wagon and have a diesel on carli ride with lockers installed and winch and out perform that power wagon get better fuel mileage and tow better all at the same time.
But again I'm a little bias to Diesels and Carli from previous trucks Ive built on the farm
That's quite the statement. Assuming similar trim levels, a diesel is about 5k more than a PW. Add even a lower end Charlie and you adding 3k. Winch is 1500 on the low end before you mount it. Due to the intercooler you'd likely have toadd a full bumper so there is another 2500. Selectable lockers are about 1 to 1200 each plus another 800 to 1000 install.
So now you're pushing 15 to 16k more than a Power Wagon with pretty much every warranty voided. Not to mention, in use, that heavy diesel would be felt up there but I'm sure the Carli would help. It would be a cool truck but it's not exactly a fair comparison either.
I just bought my PW a few weeks ago. I went back and forth about buying a diesel and doing the above. It's just out of the reach cost wise though. Not to mention, usually diesel is more expensive in my area negating any mpg savings and there is more maintainance.
