Rear Slide Interior Seal

[Colt099]

Hello, I recently purchased a 2010 Jayco Jay Feather EXP 26P travel trailer. I purchased new from the dealer as the unit had never sold. This trailer has two slides: (1) a side slide for the dinette; and (2) a rear slide for the king bed - this slide comes out the back of the trailer.

I noticed that the rear slide does not have a seal on the inside of the trailer that goes tight to the inside of the rear wall. The side slide has it - it's wrapped in white plastic and goes tight to the side wall when the slide is fully extended.

Can anyone that has this trailer (or a Jayco with rear slide) tell me if their rear slide has an interior seal. Thank you in advance for your help.
