2 hours average per week seems about right. Rarely are we anywhere without trailer which has champion 3500. Virtually every time we parked the champion runs to supply power. It likely has over 10 times the hours as it runs with quick fillup and oil check twice a day. At replacement cost of $325 was good investment. The Onan is most costly and is used mainly on road for a\c in hot weather. We always travel witth dogs and if they start to pant, we cool them. I did add an inverter to run tv/bluray/ps4 when traveling with grandsom (s) in cooler weather. The original house batteries are due to be changed, will do before winter series racing. That is closest we get to boondocking if we get there early for good spot.
