We have a 1.6 cu ft. Danby fridge (110v) in the basement of our Jayco Whitehawk(installed option by Jayco). Have used it once and was underwhelmed. Temperature control set to near max. cold and it produced barely cool beer and soda after hours of operation. As nice an idea as it may be, I think the problem with the basement fridge may be the manufacturers (at least this Jayco model) make no provision for heat dissipation from the refrigerator's operation. The refrigerator evaporator coil is trying to dissipate heat from normal operation into a closed space, made even hotter with the sun beating down on the TT all day.
