Front compartment on the entrance side is the battery compartment. Two metal bars holding the battery box and vent line to outside.
We ordered the ground control and residential sized fridge, in our case the compartment is empty except for the ground control/ control pad.
The dual battery box, vent line to outside, battery cutoff, and inverter are then in the forward storage compartment.
We really like our residential fridge. Sure beats the 6cu ft. fridge.
I'm thinking of maybe mounting a propane base tray on the two metal bars and using it to transport our
spare 20lb or 30lb tank that I use for our grill and stove instead of puttin it in bed of truck.
