Eugene,true to a point,in the RV on the road they bounce around so level less important.

Our 1979 3 way refer would freeze still in 100 + weather but that was on electric,you are right,less cooling on propane but I dont recall ours ever getting warm on propane,just wouldnt freeze things very well.

On 12 volt its use was pretty marginal for sure.It certainly had limits,very good point.Thanks for pointing that out.

Some work arounds are keep direct sunlight off backside and a computer fan over condensers helps too.

Friends indoor old Serval type was a fine machine just on propane.They are fine machines that last forever but.....

Im much more impressed with electric models,they are better appliances overall in offgrid/grid down scenarios IMO.

But I wont knock anyone getting propane,they work and work well no doubt about it.Just breaks down to how it will be used for YOUR particular needs as you percieve them,thats variable and the right answer is what works for you.
