Learned something new as well last weekend. Had had the Mhome at the shop for some body work repair. Picked it up and batteries dead..found the solar power charger had burnt a wire. Not that big of a deal so they plugged it in and we brought home and went camping. (Ordered new solar charger) When camping found out Fridge would not work on AC. No big deal but no ICE if not on AC. After a few days of searching turns out the GFCI had tripped in the bathroom and that controls the AC to fridge :E So long story short the Body shop did some welding on an outside door and Hubby assumes they grounded to the MHome and blew the panel.
