I have a small 50 watt Siemens panel I mounted on the roof of my Westy.  It
just barely keeps up with my 12 v cooler and my ham radio.  I believe it to
be prudent to not utilize the main battery for anything other than running
the engine, lights, etc.  I have a small deep cycle coach battery that my
camping stuff uses.

Wondering whether anybody has setup a solar panel on there westy instead of
hooking up a second battery - If so where did you get it - how much was it -
difficult to install?
