I'm hoping to get some help with trim pieces on my 1970 Aristocrat Lo-Liner. The first two pictures (one with a ruler for scale) show a plastic piece that sits on top of the side walls and joins to the roof. The small channel holds the ceiling plywood. The third picture is on the vertical edges of the side walls and connects to the back wall. It's a reverse "Z" shape. I can't find any other mention of these on the forum or online. Are these pieces available? What do I do if I can't find them? What are others using, or doing, instead?
I don't think you will find these plastic pieces. The 70s trailers were built differently, so we are not familiar with many of the "new" parts and pieces.
To do this trailer correctly, I would repair the walls, then lay the plywood over the top of the wall with gimp to cover any gaps. This would be a lot stronger than plastic clips. Remember, this type of trailer is repaired from the outside in so that you can access all the rot. It should be easy to go back a decade and make your trailer stronger.
Interesting but not surprising they went to plastic. My '67 Compact had the same trim piece as yours at the ceiling / wall juncture with the exception mine was made out of aluminum. In rebuilding my walls, I've allowed for the ceiling panels to be placed on top of the walls as Vikx suggested thus eliminating the need for this trim / molding piece.
Here's a shot of the original in place before I removed them. Note the piece to the right is the aluminum piece that transitions the overhead ceiling panel to the front wrap (ceiling) panel that goes down behind the cabinets. Hope it makes sense.
