The sway bars I have are Husky friction sway bars. I have one on each side as suggested by the manufacturer for my size camper. My tongue weight was within range. About 11%. I have a tongue weight scale and use it before each trip. I am at the upper end of acceptable with payload but I don't exceed it and my truck is capable of towing 3,000 pounds more than I am so I'm within the limits. So is it speed up and apply trailer brakes or slow down and apply trailer brakes? it seems there are two answers in this thread???? I was taught to reduce speed by letting off on the gas and to apply the trailer brakes manually. That's what I did and I was able to get things under control.
