New truck Break-in period before towing

I've just taken delivery of a Ford F-150 with the 3.5 L EcoBoost engine, and I was wondering if anyone has any helpful tips and tricks for the break-in period before I attempt to hook up the TT for our first trip out camping.

Many posts say to run at least 500 miles before towing, and I've seen some as high as 5,000 miles. I'd like to solicit a bit more advice, since most of our trips will include at least one mountain pass and lots of elevation changes. I usually keep the speed down a bit when towing anyway, but there may be other factors to consider as well.

every little bit helps!

I get my F150 EB tonight. When I read the book it said 1000 miles. I won't be pulling anything until I get that 1000 miles on the clock. It's hard to wait (mostly because my trucks sit during the summer while I ride the bikes) but I'm going to anyway.

For the F-250, it is 500 miles. It is in the manual. Read it, learn it, know it. You can go to the Ford site and download the manual which makes it easier to search.

Hay Dave - Congratulations on that new truck. One tip to help with the break in is to allow two or three short trips for the gears to warm up before taking the TT out for a long outing. I've had two vehicles re-geared and in both instances the shop recommended a break in period for the gears of 500 miles before towing and doing a warm up cool down cycle a few times before towing for any long distance. Apparently this warm up cool down period allows the gears to properly seat and contributes to the longevity of the gear set (in the differential). So, with my last two new vehicles I ran a couple of short trips with the TT before hitting the road for a big outing.

Have fun. I would be curious your impressions with the new EB after your first outing.

Just don't baby it. The ECU/TCU is learning your driving habits during those first 500 miles and if you go easy on it, it'll shift weird later. I had to have mine reflashed for an update and the tech told me its better to drive it hard during the learning period and go easy later than vice-verse.

Not that you'll have a problem getting heavy on the go pedal... that engine is FUN!

My last gasser said to go 500 miles before towing anything and then to tow the first 500 miles at 55 mph or below. The moral to the story is to read the manual and see what it says. Especially with the new EcoBoost technology, convential wisdom might not be correct.
