break in period before towing?
Hey guys, don't have my truck yet so I can't check the manual. Got a 6.7 coming the end of the month. Actually scheduled to be built a week from today. Anyways, we traded our 250 V10 for it as we also have a heavy new 5ver on order coming around April 1st. So, what is the recommended break in period before towing anything heavy? I'm not super worried about it as I am in MA and the new trailer will need to be towed home from MD. The ride down there empty will probably suffice, but wanted to know what the official word was on break in. Thanks.

My truck is a work truck and tows something almost daily.
When I took delivery one evening, I knew I had to tow my Mini-Excavator to job the next morning. So I took the truck for a 100 mile spin around the city that evening. Needed to get to know the truck anyway.
When I hooked up the next morning ( trailer and equipment was around 10,000lbs) I made sure to really baby the truck all day. Easy starts and stops. There is so much power in these trucks, that it didn't really feel like it was working any way. I continued to baby any loads I hooked up to for the 1st 1000 miles. By then I decided the truck was settled in and stopped worrying about it.
I would try to get the 500 miles in before towing. But I think there are worse things a person can do with a new truck than gently towing a trailer home. In fact I've seen too many test drives of new trucks at dealers where the test drivers are flooring the throttle and testing the acceleration on trucks with 10 miles on the odo.
The point is, I would avoid full throttle acceleration, seriously hard braking, Seriously loading up the torque by lugging the engine with full turbo boost more than an easy tow. I wouldn't hook up a 15,000 lb trailer and tow up an ten mile 8% grade, but a little freeway mileage on level ground, I just don't see as a problem.

The big thing they don't want is being on highway at a steady cruise. If your close to highway,vary speeds up and down, take every off ramp. And then get right back on. That is loading it plenty. As painted horse said in town with give you alot of load and rpm changes. Either will work. I personally don't like the idle time in city.

Thanks guys. Makes sense. I will have more than 500 miles on it before taking the RV home. Should have it for a few weeks before the RV comes in. Then it's an almost 400 mile trip to pick it up. Can't wait to see how it does. Dry weight of the 5ver is 11950 so it should be a fine test on the way home. Can't wait!

The thing I notice when pulling 5vers and other high profile trailers is the hotter EGT temps. I can roll down the highway at 70 mph with a low profile 10,000 trailer and see 600° temps. Hook up to a wind sail of 5ver and my EGT jumps to 800+°. If you are watching you will see your turbo boost is also running 5-10 psi higher. So even though you are driving the same speed with the same weight, The extra wind resistance of the high profile trailer causes the engine to work a lot harder. And I think that is what Ford is cautioning against during the initial 500 miles.
Same thing with pulling steep grades or fast acceleration.

To the OP: throughout your break-in period be sure to vary the throttle (load) and speed...and to take it on drives long enough to get the engine up to operating temperature...I would avoid cruising down the highway on cruise control at a steady speed for long periods, and long periods of engine idle. Many diesel mechanics in the past have told me that the best way to break one of these newer engines in is to hook up a light trailer and take it for a drive on a highway (avoid the freeway) with some small hills...thus varying the load and throttle, along with the speed. You might want to consider some kind of monitor for engine and trans vitals...like an Edge Evolution or equivalent...always good to monitor temps when towing. Good luck with your new truck!

Thank again guys. All good info. I have to say, if I had to tow right away, I wouldn't be super nervous about it but knowing that I will have the 500 on it is even better. Pin will be around 3k. I was going to swap my bags over from my existing truck as I have had 3500 on it quite a bit over the last three years, but they won't fit the new one. I am going to see how much it sags on the trip home and if I don't like it, I'll order new ones. I should have some drag increase going from the TT to the 5th, but I'm thinking the nose design of this one will help a bit. Keeps me from needing a slider too. Check it out if anyone's interested. < Heartland Toy Haulers | Heartland RVs There's a pic of the trailer's front at the bottom of the page on the right. Anyways, again, all good info and thoughts people. New truck in 3 weeks. New trailer in 5. Scott, will be rolling heavy through your neighborhood in soon after!
