Well just figured I would update you all on the truck. I now have just shy of 21,000 on it. I bought the truck brand new on 2-9-15 with 17 miles on it, so at 21 weeks of owning it I am at 21,000 miles, right at the 1,000 a week I figured I would be putting on it. Overall average is 27.5 MPG. Towing is lower than I thought, around 14ish. These are off of the idiot box, not hand calculated.
I am still impressed with the truck, the ride is great, the mileage is awesome, but if you tow a lot or tow heavier it is not the truck for you. With 4 yards of asphalt millings on my trailer I could not go over 50 or the trailer would begin to sway bad. I think it has to do with the suspension of the 1500 vs the 2500. If I was only keeping the 1500 I would definitely get sway bars as well as air bags, but I am almost done fixing my 2500 so the towing with this truck should cease to exist as soon as I get the 2500 back on the road.
I have changed the oil, oil filter, and fuel filter every 10k miles, so far nothing looks out of wack, and even though it suggests fuel filter changes at 30k, I definitely would not wait that long. My fuel is filtered at the pump at the station into my transfer tank, transfer tank into storage tank, storage tank into truck, and truck into motor. The filter still looks dirty after all of that filtering, and the station is known for good clean fuel that I get it from.
The oil change with oil and fuel filter cost me about $125 each time, with me doing it myself. Don't plan on saving money on oil changes, the dealer quoted me $250 for this same service, FYI.
I am going to look into transmission service, they claim lifetime oil life without service, but I doubt I trust that.
