Sierra 371REBH with terrible Dometic Blizzard NXT factory install

I purchased the camper new in 2017. I have a Sierra 371REBH. I have never had any issues with the a/c or rain leaking into the unit around the living room a/c. Last week I was in PC Beach where it was in the mid to high 90's and high humidity. With this being said, the a/c ran most of the day. After a few hours I started noticing water dripping through the ceiling joints to the point I had to use pans to catch the dripping water. I thought that the condensation tray was clogged or the unit was possibly freezing up and when it would thaw, the water could be blowing back through the vent and leak from there. I was wrong! Today I got on the roof and took the a/c loose and checked it and found that when the unit was installed at the factory, the a/c was misaligned with the hole(see pictures) I cleaned around the hole, filled the current bolt holes with dicor sealant and also put copius sealant over the bolt holes as well. I ended up sliding the unit about a gasket seal width to the door side and re bolting it in place. I feel pretty confident that it is now fixed and no more leaking. The leak was caused from condensation dripping into the area where air goes into the distribution side and blowing back and leaking out through the ceiling. If you have issues with water dripping from your ceiling and have the Dometic Blizzard NXT that is fastened from the top and no access from the inside, you may want to get on top and take the a/c loose and check the alignment of the unit with the hole in the roof.
