I found what seems like a really good deal on the camper fluorescent light
fixtures.  They are 32.25 here: http://store.solar-electric.com/tl-171.html

These are exactly the same lights that you get from other vendors for
$50-$60 (or the dealer for more than a hundred).  I know because I replaced
the stock incandescent fixture from our '83 camper with one of these last
season, and it said "Thin-lite 171" on the inside.

(I have no connection with this outfit.  I just ordered some of these lights
from them.)

By the way, does anybody know what the wattage of the stock incandescent
fixture was?  I can't seem to find my old one to check.
