Slide Gaskets

I am fairly new to the TT world and have never had a trailer with a slide out.  Can someone tell me how the gaskets should lay when the slide is out?  Half the time the gaskets pop out and lay on the side and top of the slide and half the time they stay curled into the gap (sometimes both).  I think having them out would shed the water away from the opening better, but I think they would seal more tightly being curled in.  What is the recommended position of the gaskets?  If it is out when the slide is out, should they be tucked in before putting the slide in?  I know they need to be lubricated periodically with silicone spray but I want to be sure they give the best seal possible.  I have read much of the forum and couldn't find anything on this specific topic. Thanks for your help.

agree with furpod. Occasionally they do not come all the way out so I always check to make sure. I think it would be a big positive deterrent with rain when there out.

just my opinion, always bring some sort of ladder, never know when you might need, takes very little space, a good way to check top of slide before rolling it in to make sure nothing is up there.  can serve a bunch of other purposes too.  i also make sure those gaskets are in when i bring the slide in, they also can occasionally stick a little; like all else have mentioned, keep them lubed.  hogone
