At $5,000, you could replace a regular dishwasher every year just for kicks. Not worth it!!! Well in Texas it would be a problem with sun damage and hail smacking into the front panel of the thing, but I don't think they are that durable.
How silly--again-just take the dishes inside and use the one in the kitchen.I think that was one of the reasons trays were invented.for $5000 could buy some rather nice serving and dish trays.
