I have a hybrid travel trailer with layout/swing out tent beds and the plastic bungee catches that hold the tents snug to the frame are sun-baked, broken and missing. I don't know what to call them (well under my breath maybe) and i don't know where to get them. Does this make any sense ? Our trailer is a Starcraft TravelStar. Anyone have any suggestions on what they are and where to purchase replacements? Thanks!
