We just mounted a Swagman Roamer LT set of bars to our camper. Seemed to feel solid. Made it to a campsite with two Kayaks. Opened the camper, and looks like lag screws are just in the side panels of the roof! The lag screws came down tight and but hard. Feels solid. What could I be anchored in? Wondering if I need to move the mounts further inboard and use carriage bolts and a steel plate on the underside of the roof? Any advice welcomed! I’ll try to figure out how to upload something some pics from my phone. First timer poster here.
