One of the biggest problems with hauling a trailer or camper is sway. The same can hold true with poorly stabilized RVs. That is why Camping World makes sure to carry a number of sway bars and stabilizers. Few things are more nerve wracking than trying to maneuver a vehicle that is rocking back and forth, endlessly.
Sway bars work by minimizing the back and forth movement of your vehicle, much the way shock absorbers reduce up and down movement. This keeps your vehicle from rocking as you go over bumps or around corners. By tying together the suspension and the frame and distributing the weight more evenly, you gain better control over your vehicle.
