An update: After reading all the recommendations, evaluating space in my car, counting savings, adjusting for high gas prices I bought the 42Qt Vevor refrigerator for pretty much 1/5th of the main brands (ARB, Dometic, Engel) and about 1/2 of the other brands (Iceco, Wynther). The refrigerator is running constantly for over a week in my garage cooling water and beer. I was a bit concerned about the lid with no latch but it is magnetic so shouldn't open or bounce even when off-roading. Will have it strapped anyway. So far, all is good. Hopefully, it survives two week long camping/off-roading trips this August and continues to server as a backup refrigerator in the basement/garage till next summer adventures.
