Went and picked up the boat from my storage unit in needles last night. Turn around trip and came back. Weather was insane. I have never driven in wind so bad. Or the rain. My 2014 silverado with a 5.3 had a hard time pulling 65 up one of the mountain ranges. Towing the boat.
I pulled a 32 foot travel trailer up the Cajon at 80 with this trick and had more to go. It was that bad.
