As the title says, I've had my truck for 17 months and 24,000 miles. Ordered it in 2012 (arrived April).
My hand calculated lifetime average MPG is 16.4 mpg. My best observed is 20.4mpg. I think these are very respectable considering the mass and aerodynamics of the truck. I am pretty consistent in the 16-17 range. I've pulled 15,000 with it and most of my normal driving is a 7 mile commute to work. I do let it warm up in the winter, which I've seen 12.5mpg on a tank of fuel during coldest months.
No complaints about how anything is holding up. I mean, yeah, it's a 1 ton truck and I know it won't ride like a car. But, it's our vehicle of choice when we travel because it's comfortable. When I replace shocks, I may try another brand just to see the result. But, other than certain highway expansion joint spacing, the ride is good. When I rotate the tires, everything seems tight. Tracks straight and true down the road - I can let go of the steering wheel on straight stretches and it holds straight.
Tires will make it to 35K-40K if I were to guess. I have the 20" Michelins. No cracks. Just wear. I rotate at each oil change (3K-5K).
Engine and transmission are a great combination. I am not tuned. I run Shell T6 and have oil analysis done. Everything looks good. I change every 3K-4K and because of lots of idling and short commutes, I run the synthetic. Walmart carries it...no problem. Oil filters purchased from dealer or online (cheaper).
I changed fuel filters at 23,000 and they looked good. Have religiously drained prefilter and find no water. I keep fuel receipts in a file. I do run DieselKleen for lubricity/cetane improvement. I checked MSDS sheets from the major brands and didn't find one that seemed to blow me away more than the others.
Interior is holding up great. No annoying creaks. Leather is great. I use Meguire's leather cleaner and conditioner monthly. Other than that, I treat it like a truck and get it dirty, but it comes clean. No cracks or issues like that. Holds up well to small children (LOL).
I undercoat annually with Fluidfilm and the underside and frame has ZERO rust. I powerwash the undercarriage in the spring, drop the spare, and reapply. I hate rust. So, this does the job. I did the same with my Tundras (I am in the northeast - so salty roads during the winter) and they looked great underneath after several (5+) winters.
I love my 29" big rig horns that I added. They get you up in the morning
Cupholders and console - really like.
Paint- looks good - no problems - beads like the day I brought it home. I use Eagle one Nanowax and it's easy to apply and the paint stays nice.
Things I'd change:
- Oil dipstick. What a PITA. If you can read yours, God bless you. I can't tell what's going on. But changing the oil is no big deal, on the plus side.
- Air filter service - not a major deal but changing the filter is more difficult than it should be.
- More protection for oil filter. I haven't had an issue but it is fairly exposed.
- Auto up/down on passenger window
- When you order the 5th wheel prep, I wish they didn't charge $250 for the ball. Throw the ball in Ford.
- Another 110 outlet for the rear passengers - just more convenience with small children and their electronics on long trips.
- LATCH for rear seat anchoring of child seats
- Stronger exhaust brake. Hasn't been a big issue, but just a wish.
- Front corners sonar. I still am iffy about the front bumper corners and where I am with them when in tight turns like thru a drive thru. Again, not a necessity but a wish.
I'd buy this truck all over again today, even considering what's available today from Ram and GM. Not knocking them, but I enjoy the size of my truck, the power, the efficiency, and the reliability. Interior fits our family well.
So, some positive points and some recommendations. Enjoy your ride!
