I would never remove the foam in a GMC ceiling, It adds a lot of rigidity
to the
roof, The roof will buckle a lot more when walking on it. The foam is part
of the
structure. I added 200 board feet of Tiger spray foam (non flammable) for
almost
a flush to the ribs, than glued the Mylar bubble wrap over the hole ceiling
and glued
another layer of bubble to1/4" plywood, than my foam backed headliner
material.
I have only one 15000 BTU Penguin AC, it works great here in Florida.
