Technical Service Bulletin CSC-2309 — 2024 BRINKLEY RV MODEL Z

It has come to our attention that the polycarbonate plastic utilized to manufacture attic vents for the RV industry may be incompatible with the 5121 self-leveling roof sealant that we utilize. We have received reports of cracked attic vents in the field that we believe are the result of the sealant being more rigid than what is traditionally utilized. This additional rigidity does not permit the attic vent to expand and contract and can result in the attic vent cracking either along the location of the mounting screw holes and, in some cases, cracking vertically up the attic vent. Brinkley RV will pay for the Campaign to be completed. There is no charge to the customer for the remedy.
