Is lack of sealant on slide-outs normal?

Hi all,

I noticed the slide-outs on my 2021 357MDOK lack any sort of sealant where the aluminum siding meets the inside wall of the slide (for lack of better terms). Is this normal, and should I seal this? I get that this should be behind both seals when open.

For the most part, it's covered by a weather strip when the slide is out. I don't think it would hurt to seal it.

Mine has both gaskets, one on the slide out & one on the trailer mating wall

hmm.. interesting. I think I'll put a bead of sealant there just as a precaution.
