I have had a built in Onan 3600 propane fired generator for 10 years. I also have had the portable construction grade generators like the Champion. The Champion and other non-rv or quiet type generators make a lot of noise. Also they tend to be heavy. I have not owned one of the Honda so I can not say much about them other than theft would be my biggest worry. The after marker has a lot of key fobs, tanks, remote start, etc.
When hurricane Gustov hit the area where I live, I had three 100 pound cylinders of propane, a 12 foot long hose with a male Acme and a female Acme fitting at each end. For the 100 pound tanks, I had a POL fitting with a male Acme fitting to connect to the trailer. I ran the genny 24/7 except when 100 hours came up and then I would stop it to change the oil. Finding gasoline was next to impossible. You could find the 20 lbs. tanks just about everywhere.
Propane does not gum up the carberator like E-85 and lesser grades of gasoline do if left it in the carb a long time. Yes, I am aware of the additives that you add to keep the gas from going bad.
There are two schools of thought and what you want out of the generator setup should decide what you need. Starting the built in generator and allowing it to run the ac is one option. Look at everything and see what fits.
