ATF: North Trail - Weatherr stripping around slide outs.

I am have a leak on both sides on my travel trailer. I examined both and could minimum damage to the weather striping. It just looks like a very flat peace of rubber.Shouldn't it a bubble type?

What type, and how long are the strips? Added pictures to show what I fighting.

Okay. couldn't wait any longer. I replaced with standard 1/2 inch "D" stripping. Also found that the tape on the slide out wasn't installed properly and have creases witch can allow water to seep into the slide out. I'm using Kool Seal Elastomeric Roof Coating, to seal these seams. Worked for me in the past on other Rv's. @ coats on each seam. Anyway, I'll be ready to travel in a week.
