I have a similar LG unit (4.7 cf) in my 5th wheel.
It is fine as a washing machine. It is marginal on drying. Plan on heavy items like towels being damp when you remove them. Sheets will dry fine.
Because of the small capacity, you will need to do laundry more often.
The washing/drying cycle depending on your choice of options can take over two hours.
It has been in use for five years with no problems.
I wish I had room for one in my Axis.
