I have a 2005 Ford F250 6.0 PSD...I am pulling a 3400RE Bighorn..My question is, do you pull in "Tow Haul" while cruising at Interstate speeds. I found out on a recent trip over the same highways, coming home I got 9.4 MPG in tow haul, and going I got 10.4 MPG pulling out of tow haul. It seems like I can do just fine out of tow haul. Plus, I increased my MPG by one full mile. I have boost, tranny, and EGT gauges and I noticed no significant difference pulling at highway speeds out of tow haul. I do switch to Tow Haul in cities though.
What do you guys do?
