The reason I ask is , I do stay in my RV for long periods when working out of town, and on the off season I take the family camping for long weekends , sometimes for 2 to 3 weeks in the mountains ,etc.
And I have a Solar set up for off grid / dry camping . I am going to go ahead and install a inverter for regular loads like TV , etc but for the short periods when we want to run the coffee pot , etc I will just fire up the gen set. So what I was thinking about doing is connection the inverter output to the shore power line ( probably using a plug into the side of the RV so it can not be connected when I really do have shore power ) and If the gen set is the default then all I have to do is fire it up for 5 mins or so then when done kill it and power should jump back over to shore power which will be the inverter. unless someone has a better Idea.at first I was going to connect the inverter to a plug in the side box but don't want to have to worry about killing a breaker or unplugging it every time we fire up the gen set and I am sure the wife wont think about it either and do not want to burn up the inverter with the gen set..
