Valterra’s Universal RV Stabilizer is designed to help end trailer wobble. It’s a simple, adjustable product intended to add stability to the front and rear —– or both sides — of a trailer. The company says it sets up in minutes without requiring tools and folds down for easy storage when not in use. All-aluminum construction, aside from the included ratchet straps, means it’s light and resists corrosion. Available at Camping World.
