Why consider 12v fridge for boondocking?
So I want to offer up this question out about 12v compressor refrigerators. I'm going to post this on other forums too, so your "forum tramps"(like me)may see this spread around some other pages. Not...

How long does the propane tank need to be in sun every day to replace fuel burned to power the fridge?
what exactly are you talking about here?
My understanding is the most normal way for RVs to store electricity is 12 VDC. A residential fridge operates on 120 VAC. So to power the fridge off battery, (Stored 12 VDC) power must run thru a inverter. Every time you change the form some of the power is lost. Hell, when the compressor cycles off, fridge is not taking any power, the inverter is using power just waiting for demand.
The OP is talking about a fridge that uses power in the same form it is stored, so the changing is not needed.

You ask "What did I lose"....And then say you are trying to figure out a way to fun the fridge off of a 1LB tank... When you had a system that you removed that would have done what you are trying to do now.... My question was, and still is... What did you Gain by removing the propane? Especially since you DO want to run the fridge off propane on occasion.
1 time, in the 4 years after I removed the tank, we spent a extra night at 1 CG, instead of moving on the same day wife had a class, because I did not have a way to power the fridge while she did her thing.
For that 1 time, I for sure see no reason to have the extra 30 lbs (guesstimate) on the hitch ball. Then there is the issues that likely would develop with 20+ YO soft copper lines. (As a young man I worked a few trucks with copper air lines. I can't stand under why RV industry has not come up with something better)
