Talk to me about washing machines

[Rangerman40]

So our new fifth wheel has a washer/dryer prep. I've looked online and all of the rv specific units seem to get mixed reviews, and take forever to do a load. In talking to my wife about it she's not even sure we need a dryer because she dries very little at home. Does anyone have any recommendations for a washer only? I like the idea of an apartment sized stack unit (if it will even fit), but less than thrilled about having to drill a hole in the side of a brand new fifth wheel for a vent. The combo ventless units look fairly useless to me. It's one of those things that doesn't really do either task well and is highly inefficient about doing it.

My vent is in the engine compartment. No hole outside.
I love my combo unit.
