I need 12' to simplify things but that doesn't look like a problem. I
was thinking about steel or fiberglass but PVC may be lighter. This
looks like a possibility too. Clear would allow me to see the
critters under there. We have squirrels making a nest in our gas
grill (hasn't been used in years) now. I wouldn't want them under
there.

Pvc can be heavy, could try Polycarbonate Twinwall if you want some
what clear.

Yikes! That's some expensive stuff! More than $4000 for the 12x16
deck.
