>>Definitely needs more lights inside.<<

Check out the low power halogen fixtures from West Marine who has retail
stores and catalogue (pages 538-540) @1-800-262-8464. Performance of these
halos is reportedly better because they shine brighter, last longer, require
less wattage, and do not dim with age. They are not cheap to buy but are
cheap to run and since they last longer, total cost is supposed to be lower.
Some model have swivel bases or rotate & swivel and most provide spot
lighting for reading, etc. without bothering your SO.

I wired in a small fluorescent fixture (two bulb, 12" long) from an RV
supply store and, using plastic wire ties, attached it to the bar to raise
the camper roof which allows for "broadcast" lighting...does a good job of
lighting up the interior from above with no obnoxious light in your eyes.
