Having a lot of trouble finding one. I need on that will be 54" wide. I see that I could cut one in half, but would hate to spend the money on a 2 place and waste the rest.
we made one last year for our spare single place trailer, for my nephew to use. we just had a HVAC / sheetmetal buddy bend one up out of galvanized metal and a bit of wood or additional strength across the top.
let me know if interested, PM me and I'll see if I can find the sketch I used to get it made.
