Our MH had one in it when I purchased it but I said, "we'll never use that" and took it out. Well, 12 year's later, I just installed a new vented 2100XC, and the wife loves it. She generally uses it every day when we have hook up's keeping the loads small. No more runs to the laundry. And since I mentioned this on the last thread regarding washer/dryer's, you can contact Splendide(Tony, in Oregon) and see about a scratch and dent unit. We got ours this way, saved close to 700.00 dollars and the slight damage is not noticeable at all.
