Ice Cream is easily scooped at 6*F - 10*F
To keep it frozen hard temp needs to be -5*F - 0*F
Most RV absorption fridges freezers are at 10*F - 5*F
WHen an RV absorption fridge has been properly installed, has 0 clearances, no dead air spaces and good Draft it is quite capable of sustaining 0*F or lower temps
Unfortunately, RV MFGs do NOT install them properly....too wide of clearances, dead air spaces, lousy draft.
But they do shine when it comes to Bells & Whistles
