Moving forward, SikaLastomer®-714 will be used as the sealant for roof-mounted components, including roof vents, skylights, and TV antennas. This change eliminates the use of self-leveling sealant around roof components, providing a cleaner, more refined appearance while reducing concerns related to cracking or discoloration commonly associated with traditional sealants.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034215-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034215-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11034215","components":[],"codes":[],"topics":[],"vehicles":[{"make":"WINNEBAGO","model":"EKKO","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]},{"make":"WINNEBAGO","model":"NAVION","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"WINNEBAGO","model":"SUNCRUISER","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]},{"make":"WINNEBAGO","model":"SUNFLYER","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]},{"make":"WINNEBAGO","model":"VIEW","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
