I have a non working colman 500 watts ac and 12 v dc you could only
use one side at a time. it was a noisy thing to run and was in a 10 inch 
clube space gas tank on top, I had it in for waranty service after getting it 
back ran a week, same ploblem jam in altenator part.
so its just lays around now. it cost around 500.oo new 
now I only use the big power plants, plus my 140watt power to go
run off my batterrys and panels.
