Looking at photos on GOOGLE SEARCH I would look at the panels under the OVEN abd the GRIDGE. I also notice there is items under the raise up bed...
What you are looking for is the Power Distribution Unit with 120VAC Circuit Breakers and 12VDC Fuses. In the bottom of this Distribution Panel panel is the CONVERTER/CHARGER unit.
In the travel trailers they are usually found under the Oven or Fridge close to the floor.
Another possible place would be on the walls of the storage bays.
Your house battery cable will go directly to this unit if you can trace it.
