David presented the following explanation :
I do have a lot of spare bits of wood, just not marine ply. One

By all means make a wooded cover for security, but it would be not that
watertight and in time might rot. As an alternative and maybe as well
as...

If you find one of those companies which repairs and supplies the
curtains for curtain sider lorries and scrounge a bit of surplus
material from them? It is very easy to work with, you just heat weld it
at joints corners. A heat gun, plus a metal roller is all that is
needed
to seal joints. Once done, they are extremely robust.

Not sure why it wouldn't be water tight.

Please elucidate. :-)

The water will gather on top of the marine ply, pool in the centre, and
eventually destroy it unless you put a slope on it. Then you'll have to
provide a drip edge and find some way to protect it.

Parked up trailers usually slope considerably,

You dont see too many with no jockey wheel here now.

so no water will pool

Dunno, even with those, some usually does.

even one with a jockey wheel or stand takes some effort to get exactly
level.

But since few covers are domed and most sag a bit, there will still be some
pool.
