Diesel gen is the way to go IMHO - especially if it is a low speed 1800 rpm... they are super quiet and will last forever. I have had the same thoughts for our next camper... go 5th and get gen prep, install diesel gen set and use 7.5 gal marine style fuel tank... keep two tanks and switch to fill the empty... there is almost no mechanical noise from those units... very fuel efficient too..
