Stored my RV for the winter and took it to service dept. this April 2024. They conducted a computer scan and the ABS pump is defective. Similar to the first complaint I read about ABS systems on this site. Vehicle is a 2017 Chev. chassis converted to a Coachman Leprechaun RV in 2018. I am the original owner and vehicle has 30,000 miles on it.
