Cost of propane vs gas generator.

I have a Champion dual fuel rated 9000/8000 gas, 7000/6300 LPG. My intent was to never put crappy corn laced gas in it unless I had to. This is for home backup power. I recently has to use it for camping when my Onan failed. I wasn't concerned about the noise because most folks were running open frame generators but it sure is loud. Normally for camping I use a smaller inverter generator because my 5500 Onan is simply more than I need unless I need both AC's. Since my new Champion 3500/3100 has remote electric start, it is just as convenient as starting my Onan. My TH has a 30 gallon gen tank and a 30 gallon fuel station so I can go 3-4 days if I run the Onan 24/7. I only do this once /year when we go to the lake and it is 110+. LPG is 1.50/gallon where I live.
