Sarge, over the years we have done a bunch of boondocking and actually prefer it as it's typically more secluded and quiet (woods, not the NASCAR field, LOL). We've always used the Norcold fridges and got another in our current coach. From our experience, they are efficient. If the fridge, furnace, stove and hot water heater are the only items pulling off the propane your good to go. However, if your gen is propane and your going to run it a lot, your not gonna make it. I've had both LP and gas Onans and there are pros and cons to both. Two full 30lbs tanks last about 2 days with the gen constantly running. In either case, when boondocking, we always make sure both LP tanks are topped off and full. Enjoy the race.
