Heather,

I'm sure other folks will chime in on books for operating your mom's camper
fixtures. As far as signs, BTDT. Take a file on disc to your local sign shop
and have 'em cut you a vinyl sticker. Comes out first class and you can
apply them yourself with some focus and concentration. See:

http://www.customvinylgraphics.com/applyingvinyl.aspx  for a how-to. Good
Luck.

A thinker sees his own actions as experiments and questions--as attempts to
find out something. Success and failure are for him answers above all.
