So I got the rebuilt roof back on my super-cheapo yard-sale Jayco, put the canvas back up, and now I'm working on cleaning and other details. This is a 1984 Jayco J-series 705-- a little economy-size Pup. There are two things in the popup that I don't know what they are for. (<< wow great grammar, eh?) 1) Piece of hammered aluminum about 7" x 9", the same stuff the heat shield for the stove is made of. I thought maybe it was another heat shield for the side of the stove, but there is no apparent way for it to attach. Then I thought, perhaps it was a cover for the sink, but it doesn't fit. Maybe a hot plate, but the heat would just go right through it. 2) A line of bungee shock cord-- same cord as is used to hook the tent ends of the canvas to the bottoms of the bunks. But this cord has no apparent purpose. It runs level with the bottom of the canvas, along the entire non-door side of the Pup. It's in the interior of the Pup, but does not run through a channel in the canvas. It's just *there*. There are a couple of sharp-pointed drapery hooks stuck into it. Is it original? If so, what does it do, why is it there, and should I replace it with fresh new stretchy cord (like I did the bunk cords)? Any ideas?
