Closet was modified to hold a 5000BTU window A/C unit. The exhaust is vented out of the side of the trailer (through a duct fashioned from reflectix), and fresh air comes in from vents added to the floor (one of which contains a tube where any excess condensate also drains out).

Engel SB-70 fridge was installed and runs completely off the 100W solar panel I installed on the roof. I have no converter in my scamp, only a charge controller connected to the solar panel to maintain my battery.

Stock door lock replaced with fastec lock with deadbolt - much more secure. After removing a small section of the closet mounting flange to allow the latch to fully engage, I used the strike plate that came with the lock mounted to a small block of wood that I attached to the closet.. it seemed the easiest/cleanest way to manage this, I've seen others use modified corner brackets, but I didn't want anything metal sticking out into the doorway.

The original door lock would lock/unlock with any key that fit into the lock, so I suspect that the tumblers were jammed within the lock mechanism, making it essentially useless for security. I also had to cut the old lock off because the sides wouldn't separate - it was solidly rusted together.
