Two way for us too and here's why; Our last RV had a two way that worked flawlessly for it's entire 13 years. I even tossed out the temp gauge I had in it because I just never needed to do anything with it.
That and the fact that resi fridges have a life span of 10~12 years these days. It's shamefull but true.
I can rebuild my RV fridge for ever but replacing a resi fridge can be a huge job.
I also want to leave open the posibility of dry camping on rare occasions and I don't want to load up hundreds of pounds of extra batteries or invest in solar that I otherwise dont need, just in case I boondock.
So our choice is a RV fridge.
YNMMV.
