New low mile truck,Long trip

My 17 6.7 has about 1100 miles on it now and I’ve been varying my speeds during this time for break in per the owners manual.

Were about to take our first family trip in it unloaded about 1300 miles.

The manual says basically after 1000 miles just drive it how you want.Would you guys just set the cruise now and just do the trip or you think I should still vary my speeds for a bit longer?

set the cruise and let it ride.....you will be fine....

On my 2015.....i didn't use the cruise the first 500 miles...when it passed 500, have used cruise as needed....not a problem in the last 4 years and 36,0000 miles

My 16 had 200 miles on it when I took it to North Carolina (1200 miles or more) with a heavy truck camper on the back.. I would vary the highway speeds a little.. being summer the temps went up and down ..up to 212 deg the most then I would pull off for fuel when not too low just to vary the speeds.. and let it idle while refueling,etc to cool it down naturally so to speak. In North Carolina being **** guy I changed it out to Rotella synthetic at my cousins.. then drove across the USA camping and back.. total of. 6k miles..Now have 95k bumper to bumper perfectly trouble free miles on it..

Definitely good to hear about your road trip on your '16 with 200 miles. I picked up my '18 350 SRW last week and next month it's pulling our tow-behind 35' toy hauler/travel trailer to from VA to OH to NM and back. Guess I'll need to be mindful and vary the speeds some.

Have a great day all!

We bought our 2015 F-350 in Kansas while on a trip to the wild west. We were towing an 8000# trailer and made a last minute decision to trade in our truck. So we bought a new truck with 45 miles on it and hooked up and continued on our trip of 12000 miles. Didn't hurt a think and still going strong at about 65k miles. It can handle anything you choose to throw at it.

I bought my ‘16 dually, drove 300 miles to my loaded triple axle enclosed gooseneck @18000 lb, hooked up, hit the highway, set the cruise @ 68 and promptly made 2000 miles. Still have zero issues @40,000 miles.

When I bought my '16' I flew into Marshfield, MO, the dealership sent thier courtesy vehicle and picked me up at the airport went back to the dealership inspected, test drove, payed for truck then started the 800 miles drive back towards Texas hooked up 5th (15.5k) and away we went. 25k on it now no issues.

Hook up and enjoy your truck.

My point is they recommend taking it easy on new diff gears so they wear in correctly. Setting them in with a heavy load makes differential techs cry.

Just a small update,I wanted to make another thread about the trip but with my computer still down doing pics and stuff kinda sucks.

Anyway we went about 1500 miles round trip and the truck exceeded my expectations!Very happy with it,Ran between 75-78 MPH and got 19.1 for the trip at those speeds.I had two regens on the trip that I watched on my new CTS 2.I didn’t have a trailer but I had a few things in the bed.

Having the CTS 2 and being able to see how the Truck was behaving for the first time was very cool and like others have said in the past it’s kinda of confusing at the same time.Every regens seems to be different if that makes sense.

The first Regen started at 100% load and 8.30 GPL.No indications it started (Which I knew) but I saw the light come on on the CTS.

I couldn’t believe how fast it burned off from 100% to 60%.I thought I was literally gonna have a five minute Regen.It was that quick.But then from 60% it went down to 6% and stopped with the GPL showing .30.Now that part took a LONG time.The whole Regen lasted 39 miles.I was alittle disappointed it took that many miles to burn.I hoped it’d be much faster than that.I imagine having a heavy trailer would take a lot of that time off.

The second one was coming back and started at 91% Load and 7.2* GPL.This one was different as it burned down quickly in the beginning as the last one but then slowed tremendous around 60% load again but consistently continued to burn down.Now this one for what ever reason stopped at 30% load but with the residual heat in the DPF it continued to burn down to 17% load and ending with a GPL of 1.20.This one also only lasted 27 miles.

Not really sure why the two were different as the speeds and conditions were the same.Im not concerned about it as I’ll continue to let the Truck do it’s thing.I just like to know what’s going on without intervening.

Again like I said,This Truck is absolutely amazing!Guys That don’t have a 6.7 reading this it might sound like a pain in the a** or just too much too deal with.I can confidently tell you it’s really a non issue.If I hadn’t had the CTS 2 I’d never knew any of this happened.I don’t think I mentioned that from my 19.1 MPG for the trip,With two regens it dropped down to 18.4 and then came back up.

Well I hope this is somewhat interesting to read,I know it’s not much...It’s the short version of the driving part but wanted to share the experience!

Happy 4th eveyone!!!!

OK, how many big rigs hook to loads of 80,000 to anywhere upwards to some well in excess of 120,000 lb with less than 10 miles on the odometer? Then the first service and inspection is around 250,000 miles.
And on these “Light Duty” trucks, there are a lot of them leave the dealer lot and get put right to work. And they go 2,3,4, and some even upwards of 500,000 miles with no issues. The gears are cut, then hardened to spec. If these gears are going to “wear in” in 1000 miles; they will sure as hell “wear out” in the miles that most of them make. Yes, it is wise to not over heat them, but that holds true throughout the life of the differential.
Put them to work and don’t look back......if it going to break, break it while under warranty and on their dime; and if it doesn’t break by then you’re probably about 99.999% sure the diff will go the distance, unless it gets ran dry or abused or something like that. And that in the few years on this planet (72of them)has been by far the biggest cause of gear failure that I have seen. And that includes 49 years of various aspects of the oil industry, from drilling to production to trucking, etc. and not much equipment of any kind ever got babied.
