We have a stacked vented units. Here is how my DW got them. Time to do the washing? OK, I carry it to and from. She does washing. $10 to $12 a week. Sometimes more. Washers and driers are really dirty in many of the parks. My job, after carrying clothes to and from was cleaning them out before our clothes went into them. OK, OK, I get it. If you can handle the filth don't bother with the option. At about $10 a week times 52 we're talking $520 maybe $620 savings a year. Takes 5 years of real convenience to pay for them. Our lives were much better though. Throw in a load and go do other things. What a relief. In addition every morning we throw our bath towels in to be dried. Your choice. I wouldn't be without stacked vented units. We only RV about 5 months a year. If you can endure the filth pass the option. JMHO.
