New to truck camper/camping, so please excuse if a dumb question. I know the fridge uses lots of the coach battery power when in DC mode (so that’s basically a no no unless you want to use up your battery power quickly). I also read that when the truck is running (i.e. driving), the coach battery gets charged (from the truck power). Is this a unique situation? If not, then my question is why not run the fridge on DC while driving and then switch to propane once parked? Or, of course, switch to AC if shore power is available.
Thanks in advance!
That is what 3 way were designed for. The main issues are; the 12v is not as effective in cooling; many fridges are now 2 way with no 12 v option.
