I currently have a 2005 Fleetwood Yuma TT and the 3-way Dometic 2193 refrigerator only works with 12 or 110 volt power. My trailer service center says the refrigerator gas valve is bad and obsolete (can’t get part). He wants to replace it with a Norcold n323 3-way. Reviews of this unit do not look very good and he wants to install it for almost $2,000. Since we don’t always boondock, I’m thinking that 110 volt will take care of us most of the time. For the times we will not have 110 volt power, I’m considering a portable 12 volt refrigerator. I currently use a Walmart series 24DC deep cycle battery (690 mca) and realize this won’t cut it for 3-4 days of boondocking using the portable refrigerator (Bodega 53 qt). I’m considering purchasing a Jackery 1500 with 100 watt solar panel ($2,000). Alternately, would purchasing a 100 amp LiFePO4 battery to replace the lead acid and adding 100 watt solar panel and an MPPT charge controller be a better alternative? I would appreciate any responses from those of you who have chosen either of these alternatives.
