I have a 13'
Bigfoot 93. I have installed a 2193 Dometic. P.O. had taken the factory installed 2190 out. Why. ? Some liquids like milk needed to be put in smaller containers, laid on side because of shelf height constriction. I put a
refrigerator fan in the frig to move air around. 3x3x3 +-. Food placed near the cooling fins will freeze, meats set close stay frozen. lettuce too close will freeze. I have no space for a larger unit. I have cooler, surrounded with 2" hard construction foam; carried in toe. (stays in place during trips) bottom and sides taped together with "Gorilla duck" tape. Lid removable. Foam surround is measured to allow cooler to be lifted out. We use the square chocolate nut bottles from Cosco, frozen at home, small size 6x6x8 high ( just a guess ). Foam is great in extreme Ut. heat. We also have a portable Dometic Frig. smaller interior than2193, top loading, will freeze things left to close to cooling fins does not have a regular freezer function RC 4000. It has wheels, runs on 12 volt, or
propane. (just get the tiny gas bottles. or larger if used all the time). carry in trailer during travel. (can be set out when not in bear country) The large non portable ,cooler ( left in toe ) holds larger objects, then separate into smaller amount then to frig. Food can't stay in tow for a great period of time in freezing temp. unless temp. warms in toe some times, never leaving cooler to get too cold. Insulation holds ambient temp around cooler away when left for short time as temperature gets freezing, or warmer during travel. Holds temp correct during long trip periods in heat or cold. My friend has a
Scamp; decided to not up grade to a frig because he felt cost did not justify the amount of time used yearly. It came with a cooler installed.
Sorry I am running on.
