Going to install Maxxair. I obtained a pair of PM roof channel adapter plates off ebay. They sandwich the roof skin and accept the fan mounting screws.
I notice that many of the installs use wooden support framing attached to the stringers. Are these recommended for the Maxxaire or is the roof skin and interior trim collar screwed to 1/4" plywood headliner enough to provide a secure mounting.
