The genny is gonna overheat big time in that insulated enclosure.It's
not just the engine and exhaust. The alternator and inverter board also
generate heat when loaded. Suggest 2 4" 12V muffin fans, located 1 at
either end, one blowing in, and the other blowing out, for air flow.
These can be inset in the case, with an eave of fiberglass over them on
the outside to protect from rain. Connect the fans to the 12V sockets on
the genny, so they run when the gen is started. Hard to tell from the
pics, but it looks like you can relieve the inside of the lid more and
close it completely.This would be desirable with the fan setup.

Thanks for your advice and also the pictures of your gen-set. Clever!

I intend to buy a couple of muffin fans today and also create more
ventilation holes. I like your idea about creating a larger hole on
top of the lid. That would allow it to close tight once we resolve the
ventiliation issues. The seat cover covers and insulate the top
sufficiently.
