we do it all the time, and did with the fridge in our little popup too.
I suggest visiting the site arprv.com
not so much to read the sales pitch or to buy necessarily, but to better understand these fridges. he has tons of info posted there
I can't speak first hand to confirm any knowledge about the problems of which this product touts to be a solution.... and can in no way prove that the product works.... but to me, it all does seem plausible, and seems to be a well researched product...and I am a happy customer.
Still, my bigger point is to educate yourself about the fridge and how it works.
