Eric,
Here are pics of the cupboards inside my trailer. The overhead cabinets have batteries, soap/shampoo, flashlights, cards, dice, bandaids...you name it, it's up there!
The back cupboards are used for tv/dvd player, clothes, fans, towels, etc. Since I didn't get a footwell table, Bob made me a table to slide out from underneath the cupboards. We use this to play dice/cards or set a cup of coffee, etc.. on.
Find good fasteners to secure your cupboards. Ours have to be strapped shut or they open and things spill out.
