I have the same problem, between the outer door opening and the D-ring seal, it gets dirtier than he**, but as you, nothing gets inside.
As for the crap on the front of my rear fender flare, it gets really nasty on snowy days. From the top of the flare to the bottom, I get this snow/salt/sh** slush from the roads and it builds up on cold days to almost an inch thick. It melts when it gets warmer, but it looks really bad.
I have noticed it is common on all H3s in this area, and sure it happens anywhere there is this type of slush in the winter.
If you look at the GM mud flaps, the do not hang down that far, and also, the outer 1 inch of tire tread is not covered.
I'm hoping the Husky is wider, and about two inches longer, it sure appears that way in the photos online.
I'll take photos of both, but not sure if I'll be able to get a shot of the slush, since it is supposed to be in the 40s this week.
