If the seal does not make contact and has a gap dust, bugs, a/c and heat will all pass through. Good luck and hope it works out for you.
I get what you are saying since the OP had a leak while the slide was out but slide seals are around "flange" areas on both the interior and exterior of the slide. Of course that is not the wiper "seal" since that is not a seal to keep out a/c, heat or bugs, those wipers seals are only for removing water while the slide is coming in.
Here is a thread I started which was something I found on my TT when I bought it. There was a small metal dam that is supposed to actually keep water out and direct the water towards the sides and off. However, when the slide is out and the TT is not properly leveled side 2 side, best would be slightly off level and lower on the slide side, during moderate to heavy rain the water would jump the dam and enter the TT. I used Eternabond tape to completely seal off the exposed areas, evident in the pictures on the thread. Now being level or off level is not an issue on my TT and I have not had water enter my TT in that area since adding the Eternabond tape.
Anyway, there is a seal on the flange area of my slide but obviously, prior to the Eternabond tape, the inside seal would only seal a/c, heat, bugs but not keep the water out.
