better set up regular hookup at garage. stack machine (combo) are not as good as separated washer/dryer because washer is too small (<3.5cu ft is too small). as for decking two separated machines, I only saw people do it with front load washer. mostly stacked combo are US brands (whirlpool or GE related) http://www.lowes.com/Appliances/Washers-Dryers/Stacked-Laundry-
