Re: Friction Sway Control or Not

Oh the joys of popups. We had one and sometimes wish I had it back. First understand what sway is. Popups and smaller trailer are marketed towards beginner campers that normally wouldn't have a huge tow vehicle. Without a huge tow vehicle, a lighter hitch weight is required. Lighter hitch weight naturally mean heavier tail weights. When there is not enough weight forward the back end wants to wander all around, seemingly trying to pass the front end. Thus sway. You can also experience it when passing bigger vehicles. Getting beside an 18 wheeler, his wind curtain can push the lighter trailers to the side. When its' on the edge of a sway run away, sometimes that's all that needed to start it. The solution. Load your trailer as you would be going on a normal trip and weigh it. Weight the entire thing, weigh just the axle and weigh just the hitch. If the camper is small enough you can make a little jig and use a bathroom scale to weigh the hitch. You need more than 10 and closer to 15 % of the weight on the hitch. A friction sway controller can help control it but the real solution is weight balance.
If your on a trip and your finding yourself having trouble with this, stop and move some heavier stuff forward. Our popup had the fresh water tank behind the axle. I wanted to see what it was like to pull it with it full in case i wanted to go somewhere that I would need it. Mistake. I had to drain that. The added weight on the tail took it right off the hitch plus the slosh made it impossible to pull with it full.
You can actually calculate how much sway is possible by taking some measurements and weighing different places on the rv and tow vehicle but it can get complicated to explain. The ultimate answer to it is to load more weight forward
