Would that be enough to leave it for the winter. I saw that Jamie did start the engine and generator once a month in the winter. I have lithium coach batteries and Battleborn said I should disconnect and/ or bring them in for the winter. Does the generator run off the chassis battery to start? If not, it might be a pain to set up to run during the winter. Also do you put on a trickle charger on the chassis battery to keep it up?
First if you read your Ford manual it suggests not using any engine additives, but I am sure to get lot of flack on that statement. Short engine runs are not good for any engine. As others will suggest drive your coach if possible otherwise Change your engine oil if its close to requiring it, add a fuel stabilizer (or use a name brand gas that includes it) then fill up the tank
and let it sit for the winter. Again on the generator it needs to be run under load for 30 minutes and again change its oil if it needs it.
One nice thing about changing oil before winter is you are ready to go next spring. However to maintain your warranty Ford says 6 months or 5,000 miles on the V10 but they have increased that interval on the new 2021 V8. So use your own judgement on that. Personally most of us Drive our units very little compared to a car, so at least in my case I have a very happy V10 engine since it gets changed far more often than needed. My Diesel on the other hand is 15K or 12 months!
As for batteries, you dont need a trickle charger. There is one built into your coach. Unless you modified it when the Lithium batteries were added the coach unit charges all batteries coach and engine.
The generator starts off of the coach batteries unless you use the "Emergency engine start switch" which connects the coach and engine batteries together. It works both ways whether you are starting your generator or engine.
A word of caution on covering your coach and starting your engine. Be sure the cover does not cover the exhaust pipe on your generator or your engine. If it does (and if your Vegas is like mine it likely will) Put a warning sign on your engine and generator start switches.
Oh yes when winterizing the system don't forget the sink and shower traps and be sure your holding tanks are empty before you start the process.
