... What if you were to cannibalize the lights and permanently mount the top solar cover to the roof of the rig and ceiling mount the other half inside...
This is an interesting idea: in the end you have (tiny) solar panels on the roof, (little NiCd) batteries being charged, and low-voltage DC lights (likely LED) - a whole solar-powered system in miniature, and cheap. The full-scale version is to roof-mount a panel, charge the trailer battery with it, and power high-efficiency lights inside from the battery.
