Trailrunner 24sle towed by a 2014 Ford F150 5.0l 3.31 rear end rated at 7900 lbs with tow package installed. Has factory brake controller. TT is going to be brand new.
Alternate between using all the brakes and use just the trailer brakes to keep everything under control.
If it's a four wheel drive you can use 4x4 low range to help control your decent.
Max torque at 4000ish RPM in maybe 2nd gear on the inclines. Ford Tow mode will automagically downshift to control downhill speed. It's not an exhaust brake, but it works pretty well. You'll do fine. Just be patient going uphill and be ****** patient going downhill.

4 wheel low to control speed downhill? If it is anything like mine in 4 wheel low your top speed will be maybe 10 mph. And since you have to stop, put the transmission in neutral to shift in and out of 4wheel low, I am not sure that it a good recommendation for speed control on a highway. If you have to resort to that you probably should not be pulling anything down that hill.
