Charging issue with house battery side of class B camping van. It became somewhat apparent the system was not charging properly and quickly escalated to a high overcharge situation, followed by evidence of electrical short in smells and possible smoke in engine bay. The car was in for service for a month and a half. I am not sure the issue is completely resolved and Winnebago has been fairly unresponsive when asked questions afterwards. This issue could cause a fire. There are multiple units with similar issues. Ultimately the secondary alternator was replaced, and a recall kit applied. I am not sure what the specific kit entailed. The repair was done at Johnson RV in Sandy Oregon
