Howdy. Going through the camper taking care of odds and ends... here are a few items and questions....sorry no prizes but responses are much appreciated This is a rubber gasket thingy over the door. Any idea where i could get some to replace this one? I think this is called arrowhead rail? Who sells this stuff? Here is my green gauge height cable....anyone suggest what the best replacement could be. Is this clothes line...? Lastly, are brackets the only thing holding the sides of the roof together? Here is a question without a picture, i want to replace all the butyl tape, starting with the roof....any idea what Thickness and width I should use? thanks in advance.
