Taking a road trip in your Jeep and bringing your trailer along to camp out in is an experience that many jeepers and their families love. However, the last thing you need to go through on your vacation is having your RV stolen - and it can happen, as simple as someone backing up to your trailer at the campsite and hitching it to their ride while you're in town. Protecting your trailer is just as simple, though, with a fifth wheel trailer hitch lock from 4WheelParts.com. Easy to set up, engineered for reliability and far less expensive than a new trailer, it's well worth the peace of mind.
