I had a rough trip recently- very bad sway when towing our 12″ box pop up trailer. I had to use over ride button on electric brakes about every 5 minutes- especially bad when a big 18 wheeler passed me by or a curve in the road. Pushing the over ride button on the brakes did work ( when you do this brakes are applied to the trailer while you are driving) as did a couple of other things- like speeding up slightly.
I got a tip that solved the problem immediately and went on a 7 hour trip with not ONE instance of sway. I put a second propane tank on- the weight help stabilize. Also, I heavy item in from of the axle- i.e drinking water jugs under seats near front bunk, etc. This worked like a dream.
