Now that we have the Splindide stack units, it as become another " must have " if we ever do another rv purchase. It's just simply conveint. It does take awhile to wash & dry so you can put a load on and go enjoy the what ever.If you have any question about it's convenience, go camping with a roll of quarters and each time your DW needs a load of wash done/dried she should hand them to you... ! LOL
Seriously, we love the convenience, no worry about "hogging" a machine or "having" to get back to grab a dryer as soon as the load is done. Etc.
We have the stack set. I was looking at replacing it with the combo unit but feedback from people who had them made me think they were smaller and slower than the separate units. Mostly the dryer. We love our stacked unit but it isn't very large and it isn't very fast. I misspoke when I said earlier we never use anything else. When we gotta wash a comforter we gotta find another alternative. A lot of the campground laundries have trouble with that too in our experience.Splendide makes a stack set washer + dryer as well as their combo unit.
