I'm waiting to hear from my dealer this week if Keystone will put in a 220V system in my wash room so I can get the Whirlpool washer/dryer.
I know OZZ did his own wiring. But I will leave that to the experts.
If not, I will go with the Kenmore stackables.They are going to put in the vent for me. Cut the hole and all that stuff
MY DISCLAIMER: I do not own a Montana at this time and there fore I do not know what I'm talking about.
