[RE-wrenches] Request for Gennie Recommendation

[Kent Osterberg]

Allan,

I've got a customer that runs 5 or 6 Onan LP generators, all in the 20 
to 40 kVA range, for multiple ranch buildings. Lots of hours with very 
little trouble. The 20-kW is a little bigger than you are looking for, 
but I suspect it would be worth it in the long haul. The smaller ones 
are air cooled.
