My old Ventura
didn't have a converter or even a battery
from the factory. They relied on 12v from the tow vehicle. We had a tent trailer that came from the factory with a extension wire to run to the car battery
to run the lights. On the ventura
, I made up a battery mount on the frame but didn't add a converter as we boondocked . If you mount up a battery, you could just hook up a regular battery charger for when your on 110v. Not much runs on 12v on these little guys especially if you have a gravity furnace
. Convert the lights to LED and a battery will last a long time, throw in a solar panel
and you're good to go. (I use 2 20 watt panels)
As for the fridge, check the burner and nozzle for spider webs. No compressor on these fridges. Check the cooling coils for rust and or yellow stains (ammonia). The propane burner is probably a little screen dome and some gentle wire brushing should clean it. The propane nozzle gets cleaned with alcohol (do not stick anything into the small hole). BTW the difference in flame height from pilot setting to full on is barley noticeable. The other thing that can cause problems with these one guys is the propane regulator being out of adjustment. Should be 11 inch water column if I remember correctly and this is measured at the fridge.
