We had the Dual Hondas with an extended run tank and while it worked great it was the PITA getting them out, seting them up, then when done using them had to wait for them to cool off before restoring. When we ordered our SOB we went back and forth and finally paid the bucks for a factory installed Onan 5500 Propane. For our usage the Onan is the only way to go, with push button power.
As to Propane vs Gas, on the Onan 5500 under full load will burn a gallon of propane per hour, while gas usage is .9 gallon per hour. Granted Gas is easier to find, that means you have to transport some gas cans with you.
