6 months with no answer?
I just started restoration of my "new" trailer. The battery tray in my trailer is in the rear compartment between the toilet and the sink. On the right hand side (facing the compartment) there is electrical panel with
12V breakers and fuses. That is where the cables from battery go. I might post some pictures later, but I have last day tomorrow before our vacations in Vegas.
So if not tomorrow, than it it going to be next year.
Happy New Year.
