was moving some stuff and found 2 un-opened packs of "metal siding" plastic sheet....hmmm...what can i do wit it....(ya, this ain't a chebby either...lol)
back in the '70's my folks had a 22' Prowler travel trailer, sooo....
only prob is i have to try go completely off memory, no pics of it (house fire)
found a pic of one online that looks very similar to what my dad owned
breaking completely of my tradition of "eyeball engineering", i actually drew up a quick template for this one and a frame/plumbing layout
cut up some pieces....
...and see how it fits
