You need to replace the undersized Auto-reset Circuit Breaker that RW installs. This has been an issue for over 20 years and Lippert has even put out a Service Notice to replace with an 80 amp breaker, either auto resetting or manual reset.
At the Rally several years ago we were having a slide issue, when the Lippert Techs came over, the very first thing they did was replace the under sized breaker before even trouble shooting our issue.
