Before a long trip, take an hour to give your trailer’s tires, brakes, and bearings some love. Check tire pressure and look for any cracks or wear, then pull the hubs to inspect the brake pads and repack those bearings with fresh grease. A smooth, quiet spin on the jack means everything’s happy and safe for the road ahead.
