I know there have been numerous comments about moisture on the bottom of the door but I can't seem to find any to address our specific situation.  We went through numerous tries on our 2014 13' to completely seal the door, finally getting it nice and tight after removing the white cosmetic border, then using new weather stripping.  We're still getting a bit of moisture going down the road at the very bottom where the door slightly dips below the entry step.  I've got some black Gorilla tape on the bottom now which basically works fine, but it's unsightly.  I've head of some people putting a plastic strip at the bottom; wondered if anyone has done that, what they used and how they attached it.  Any advise appreciated, thanks!
