I just completed a round trip from Middle River Md to Savannah GA. While towing my 32 foot 5th wheel travel trailer approx weight 10,000 lbs.. I got an average of 13.1 MPH using the tow haul mode. The truck (F-250 2004 SWB CC 2wheel drive)worked just beautiful.The truck has been trouble free.It has 8650 miles on it.At this point and time this is by far the best truck I have owned.

 

This is good news, did you try not using the T/H mode on the flat....just running down the road...what rear gears do you have?

 

Hear, hear I agree. I have had fords all my life and this is the best one so far. No problem pulling.

The truck has 3.73 gears. I tryed with the tow haul mode disengaged on the level didn't seem to make much difference. I usually disengage the tow haul mode in stop and go traffic it shifts smoother at lower rpm's. I swear by this truck! I know a lot of others swear at it!! As I stated earlier this is by far the best truck I have owned. It has a build date 08-03 and an engine 07-20. it is an 04 model.
