The laundry machines in most RVs are much smaller than a typical residential machine. I haven’t seen a new Mirada in person, but the website photos make it look like the washer/dryer fits into the cabinet between the sink and toilet, at about the same height as the vanity countertop. This is not uncommon. The most difficult part of it is getting the machine into the RV and maneuvering it into the cabinet. They are quite heavy, and there are no good handholds. After wrestling with my own for a little while, I loaded the machine into my van, delivered it to a local shop, then went back home for the RV. It was quite a task for two young men to even get the machine through the entry door, and I had to remove the bathroom door from the hinges to get it through the hallway.
If you are buying a vented machine, you’ll want to take extra care to identify the correct location for the dryer vent. It is common to see a sticker or some other marking on the interior wall that shows the location to cut a hole through the wall for the dryer vent. There are too many stories of the sticker being absent, or in the wrong location, to inspire sufficient confidence for cutting a large hole through the wall. Insufficient supporting structure for the vent can lead to water leaks that will cause serious damage to the RV.
