Towing with bigger tires, 3500lbs

[Mac]

Towed my 3500lb boat today over 100 miles mostly highway, fairly flat some slight hills. Truck is max tow with a 1.5” lift in the front and .75” in the rear with Fox shocks, tires are 34” tall 285/75/17s.
Truck did well stability and braking wise but doesn’t have a lot of power on the highway, I stayed around 60mph, truck stayed in 5th gear 3500rpm most of the way, occasionally going into 6th. My boat has a low profile and sits low on the trailer.

This is pretty interesting. I do quite a bit of towing but it has all been with a Magnuson installed. Mostly my off road toys but every once in a while my Mustang. My Max tow stays in 6th for the most part and goes into 7th on the flat or down hill. Power seems very decent. I have always wondered if the sc was making a big difference. Thank you for posting. Nice setup by the way she looks awesome with the fishing rig on back
