The Allison was a big part of the reason I got my truck ..... I didn't know it was offered with a gas engine or I would have looked into that more.....But so far, I am extremely happy with the Duramax.
I think they have solved the injector problem they used to have.....I'm hoping to avoid those expensive repairs.
I am getting 11-13 MPG with my camper and pulling boat depending on wind. I am getting 16-19 empty....and I use it empty quite a bit.
If you figure 4-5 MPG or more difference over 100,000 miles, you will more than pay for the extra up front cost of the diesel....and you can put a lot more miles on a diesel before wearing it out......If you see a used diesel with 175k on it no on even blinks .... 175K on a gasser would be a big deal though.
I'm doing my own oil and filter changes to save on routine costs, but admittedly don't know how to do much else to the diesel.
When I trade or sell the truck, I will get most of that cost difference back also.
My brother has a small light travel trailer and I let him use my truck to go on a trip....He was pretty amazed by it and got a little over 13MPG on his trip...... but when he went looking for a used truck, he got a C1500 with the smaller V8 ....He thought that setup for his small camper would beat the mileage he got with mine.
He just went to Colorado on a trip and got 8-9MPG and struggled on the hills.....He is really kicking himself for not going with a more powerful engine.
