My grandparents live in a moble home and bought a Kenmore 24" stack washer/dryer. It is the small 1.5 cu. ft. washer with DA agitator. We are visiting them after Christmas and I cannot wait to use this machine. While some of you hate DD machines I love theirs and find it does an amazing job at getting my clothes clean, and the little DA really provides great turnover. They have had this machine for about 4 years now with no problems. The dryer is actually very good too for a small capacity one. They used to have a Frigidaire stacking set and that dryer sucked.
I'm assuming this is a rebadged Whirlpool laundry center. Post some pictures when you get back if you can. I'd like to see the consoles and tub shots. Hopefully, it gives your grandparents years of trouble-free service.
