Guess it should be mentioned, being a Onan generator shop for over 40 yrs, and being into the RV game, plus having the equipment, parts, manual and interest, I got into this game. All my data and record keeping were using a separate fuel supply tank, Meaning not tied into any other fuel tank, this makes it very simple to keep accurate tract of fuel burn.
Started with a 7500 Kohler 4 cyl water cooled, ( a favorite of mine) ran it over 1,100 hrs on gasoline, thought would go with the LP Gas, ran that for over 1,100 hrs, got tiredof two issues, first was the 1.1 gph burn rate and ability to buy at any price, very linited using a 65 gal tank.
Then built a 3 cyl Perkins, 12 kw, mounted a 50 gal diesel tank, The fuel burn was exactly 10 gal every 24 run time. Ran 24/7 for over 2-3 weeks.
Currently run the Power Tech 12 kw diesel, it is plumbed into the 194 gal tank, so no way to give an actual number.
Some have opinions, sone deal with facts, eh.
