So who really uses the coach dishwasher

Don't have a dishwasher....other than me! If we did have one, the machine kind, it would be used for storage.

We have an Arch dishwasher. Works great and even puts them away.

We use the dishwasher for storage.

We have one in our new to us Tiffin Phaeton. My wife did not want it. After staying in it this past winter in Florida, my wife loves it and uses it all the time. It is now on the required list.

Consider putting one in when I removed the oven/cooktop but DW (Dish Washer) decided storage for pots/pans more important.

I must be the odd woman out. I hated ours, it was a Fisher-Paykel. It never completely emptied, when the rig was first plugged in it would cycle leaving water in it. The last time I thought it needed service I just had the stupid thing removed. Now I have a really big cabinet that holds all my pots and pans! There are only 2 of us so there aren't that many dishes.

They run just fine even if not full.

We use it all the time....works great, doesn't use much water and is very quiet.

Absolutely:

Had our Contoure dishwasher (not dish drawer) installed when we had Furrion induction cooktop installed. Use both daily.
