Interior
Added a folding ham radio table, a bookshelf, a shelf under the TV to hold charging cell phones, a storage gate under the bunks, and a dog gate/cage to the lower bunk.
Customizations
Changed the air conditioner from manual ceiling controls to a wall thermostat that also controls the furnace -- eliminated the very hard to turn on stock furnace thermostat.
