Hello, and thanks in advance for any help. I bought a 2022 Mallard M26 on Saturday at camping World in Grand Rapids, Michigan. (Live in St. Louis) got home pulled into my driveway and the 15amp fuse instantly blows to the ac, none of the overhead lights works, radio. I’m thinking there is a short somewhere. Call technical assistance line for camping world and I’m told need to take it in for a tech to diagnose it. Unfortunately they can’t get me in until July 22. Is there anything I can look at or try to diagnose the issue?
