Drove the rig to lower Canadia (Ontario) to wondrous and beautiful Lake of the Woods to do a little fishing for a week. It's a tad over 1400 miles round trip up and down I-29 through the eastern Dakotas.
I towed a small 2K lbs boat along with all the supplies needed for a week on the lake.
We fought headwinds and crosswinds on both legs of the trip. We encountered flooded roads near home on the return trip.
I have "updated/upgraded" the truck to include the transmission heater bypass and a Mishimoto thermostat kit (165*F) on the cooler lines.
With that load, going 65MPH in 60/70*F weather, the transmission ran at about 168-170*F consistently.
Averaged 12.75 MPG's for the trip. (hand calculated)
Took off about 15% of the oil life too.
So that's what I did to the truck this week.
