We just finished installing our wall mounted Daewoo mini washer and dryer. If someone interested we can post some details. The cost was high but It was the only option in this motorhome and the wife had it as a hardline requirement for any camping. So it had to be done. The washer with square trade 3 years warranty is roughly $730, step up to 220 was $120, and $30 fittings and adapters from lowes. The menu was in korean but god bless google translate, we know what the differennt touch panel options mean.
The commercial for it is here
