Excellent idea Chris, thanks. I had assumed based on that page from the Avon owner's manual that the stringers had to be all metal. I'll look for some U channel and then make some wood pieces for the triangular section that wedges under the tubes.
I'm thinking I'll use ipe wood for water resistance. Any idea what wood Avon used?
