Just bought a pre-owned 2015 Aliner Ranger 12. One of the things to replace is the white strips on the extrusions that aid in the a-frame raise/lower sliding motion. Any recommendations where to purchase the strips (Aliner dealer I suppose?), and how to adhere the replacements? Further, the weather stripping has torn away or come unglued in places. Any best practice to glue them back in place (type of glue)?
