If the inverter can handle it, i would rather not mess with propane, coolant 
or exhaust.  I just wasn't sure how much power to maintain a warmer (rated 
1200W).  If necessary, a few pieces of charcoal inside the box might keep 
the electrical power low.  Customer probably don't mind charcoal smell as 
compared to the others.

Ed, did you see the link I posted yesterday to 
http://tailgatehotbag.com/id1.html ?  Their Large Side-Loading Electric 
Tailgate Hotbag measures 17x19x12" inside, plugs into a cigarette lighter 
and keeps food at 165F, all for $179 + S&H.  That's 2.2 cu. ft. each, so two 
or three would handle your 5 cu. ft., assuming you don't really need one 
large chamber.  Runs off of 12 V so no inverter needed, just plug and play.
