So I need to embace the use of propane, buy the quietest generator
possible, or only camp where electricity is available------------------
I have done the conversion this year, replacing a Dometic RM2333 with a NovaKool R4500 (12v only), and here is what I've found:
This NovaKool uses about 3.7 Amps (can be set up to run slower or faster with corresponding current usage) and cycles, so that is not a steady draw. I gained about .8 cu feet of space, but mainly the unit is much more capable in hot conditions, keeps the set temperature VERY accurately and is utterly quiet (in fact I cannot tell it is running without going outside and listening through the vent).
That kind of draw will bring my two group 31 batteries down to between 50 and 60% in 48 hours, so I added a 100W solar panel
with an MPPT controller. When parked among heavy Oregon trees it will not replenish the draw, but if it is out in the open and sunny it will run the frig and add to the charge very nicely.
My old Dometic had gotten terribly frustrating, with frozen vegetables at night and more than 50 degrees in the daytime. That's history now.
