Agreed. I had my two fans fail at the corner of the flange. Hairline crack on both..over torqueing at construction, likely at least what FV said. could be body flex too. different dates...One caught early, the other never saw the water on the floor but apparently ran down the inside in the insulation cavity. Noticed some softness : (((((((
Called FV, both replaced by FV/now dometic. 2 years p&l, 7 yrs parts, my dime labor as i was out of 2 yr labor warranty. I'm down with the latter. Used 221 on both fans, then a complete peel/seal with 221. Don't think i posted pics on 20 footers thread. Let me know and can dig up pics of crack locations and post, but the started at the screw and headed to the flange.
As for 221...dealer said what that. Now they use it exclusively.
Maybe pm bob is he doesn't see this and want to discuss. Must admit...almost went with the 3m tape but Lewster convinced me of the 221 attributes.
