A list of affected model year 2019 American Coach Dream and certain model year 2020 American Coach Revolution vehicle serial numbers appears at the end of this Bulletin. On motorhomes affected by this Product Upgrade, an older revision of the rear pipe section of the Aqua-Hot exhaust may have been installed during production, resulting in a configuration that will make the Aqua-Hot exhaust pipe exit the rear of the coach, below the trailer hitch skid guard. This could cause the exhaust pipeâ™s chrome tip to become damaged from scraping if the vehicle is driven on an incline.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10176792-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10176792-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10176792","components":[{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"AMERICAN COACH","model":"AMERICAN DREAM","year_from":2019,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"AMERICAN COACH","model":"AMERICAN REVOLUTION","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
