Ok, I am in the process of the initial breaking in on my 350. I know it says no towing for the 1st 1,000 miles.

However, I think that is for towing a heavy trailer. My trailer is around 3,000 - 4,000 lbs. How many miles should I drive empty before towing it?

Thanks!

 

I am wondering the same thing that you are. I have a little over 200 miles and just want to tow my 21 ft bass boat to the lake.

 

That is minor towing....

I started towing my 10k 5th wheel after 500 miles. I know of guys that started towing the next day after purchase.

After the 500 miles, I think a 4,000 lb trailer will make the truck happy.
Since I'm no expert, this is what the manual states:

From page 255 - 256.

Driving while you tow
When towing a trailer:
• Consult your local motor vehicle laws for towing a trailer.
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Activate the tow/haul feature to eliminate excessive transmission
shifting and assist in transmission cooling. For additional information,
refer to Automatic transmission operation in the Driving chapter.
• Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
• Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer
other than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the Tire Label or Safety
Compliance Certification Label for limitations when using.

If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lubricant if not already so
equipped. Refer to Maintenance product specifications and
capacities in the Maintenance and Specifications chapter for the
proper axle lubricant. Remember that regardless of the rear axle
lubricant used, do not tow a trailer for the first 500 miles (800 km) of
a new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full-throttle starts.

 

Thanks Ford

 

I hooked up my 13000# fiver and pulled it 1000 miles with only 1200 miles on the odometer.

 

But did you keep it under 70? LOL
