Going to pick-up our new Cardinal tomorrow which has the residential refrigerator. Will it make a difference in the life of the frig whether or not it is keep running when park (not camping) in between trips. We have some short trips plan but DW is still working so trips will be only when she has time off. We have always had , up to this point, had regular electric/gas frig. Could use some advice from you folks with experience with this new type of "ice box".
