As I get older the Electric Start and Dual Fuel for twice the run time on a tank of LPG was real enticing.
TIMES 2
I have a champion 4000 open frame that I used for my A/C at deer camp when it was 110 out. 6 years old and works fine. But I bought a champion 3400 inverter dual fual (3 fuel if you count natural gas) remote start. I bought it from Super Gen Products in Azusa Ca. from Paul Sr. 1-8generator Great guy sent me a high altitude jet for when I'm up at my property, he installed an hour meter for free. I just got back from a 10 day camping trip with the grankids. Remote start is awsome, very quiet. I only used it a few times for the microwave and the furnace in the A.M. as we have a great solar system. But for the $$ and the extra features, I don't think you can go wrong with this machine.
