Towing with 3.5 eco boost

[wapitibob]

I have the exact specs of the op vehicle but a 2020 and the tow rating is 11,300. GVWR is 7050. The 2025 has a max tow rear axle option.

There's a formula out there about derating your towing capacity for altitude, temp, weight , etc. you get the idea. usually about 30 percent. depending on where your driving. Flat Midwest at 70 degrees or over 110 degrees crawling western grades.
Like someone early in the post , it's the heat that gets them.

And keep in mind, it’s not usually the heat in the motor, it’s the heat in the transmission! Monitor your tow gauges to include trans temps. These newer 10 speed trannys generate a ton of heat! And because trucks are designed by bean counters and sold to soccer moms and dads, they are no longer equipped for real work and don’t have auxiliary trans coolers. They have heat exchangers that are often insufficient. I promise you, if you do a lot of off road hill climbing or slow speed towing (winding mounting roads) that will include lots of gear shifting with the torque converter unlocked, you are going to see shockingly high transmission temps. Keep a close eye on your gauges, and consider more frequent transmission fluid changes at a minimum.
