I finished the generator yesterday and below are some pictures showing the before, the fix and the after. We are leaving for Louisiana today and I will get to give it a good test to see if the mod worked. Sure am glad I am able to fix most things. Keystone and Onan are still pointing fingers. The 45 degree bend in the metal does a good job of deflecting the hot air. Had the bottom been cut to the proper size to start with, I may not have had as much problem as I did.
