179 water leak

Last week we went through a horrific rain storm around Austin, Texas.  We finally pulled off the side of the road since the rain and wind were so hard.  later on we opened the Pod to check things and there was water running down the kitchen (back) window, onto the counter, into the top kitchen drawer, and the top shelf of the left cabinet by the door.  there was water on the floor in the kitchen area but not anywhere else. I'm trying to ascertain some points of water entry to check. So, I resealed the outside of the window, checked the fin, roof drain for toilet, TV antenna, and sealing around the top where it meets the sides. I was wondering if water could get in the AC and run down the interior of the roof to the back window? I noticed no water coming from the AC unit inside.  the bathroom vent was closed and I have a cover for it. 

My RP179 had a very similar water leak.  It was coming in around the spoiler.  I used sealing tape around the front and side of the spoiler and never had the problem again.

I inspected the roof fin and the front-facing caulking looks good.  I did notice that there is no caulking on the back-facing part of the fin. Is that how your is? All of the other caulking looks good and I did replace the rear window caulking yesterday.
