Slide-out wiper seal

[shooodog]

Just got back from week trip to Tennessee, great time. When breaking down to come home I noticed that the wiper seal on both sides of our slide-out are beginning to tear away from where they are attached. We passed thru our service / dealer on the way home who said he had never seen that before and he would make contact with Keystone. Its a 2017 Passport 2810BH and unfortunately about 3 weeks out of warranty, so we are anxiously awaiting word. Have only done 4-6 weeks of camping in it. If Keystone gives us a problem, is there any place we can get those seals besides Keystone. It looks like all I would have to do is clear the rest of the seal that is left in the track and feed the new seal into the track. Would probably need some lubricant to help slide it through, unless it is somehow pushed into the track like spline on a screen door. Anyone have any experience with this problem? Thanks
