Not sure how much this will help, but I have the Splendide non-vented washer/dryer combo in the garage of my 3200 rig. It works as advertised, but as Rusty stated above... it can only handle small loads. As I travel by myself, this isn't a problem... but could easily see it being an issue with more than 2 people on a trip.
With the non-vented model, it usually takes 2-to-3 hours to wash & dry a load... with a 'load' being defined as 2 or 3 t-shirts, some socks & underwear or a pair of jeans. When doing heavier items like jeans, I try to never wash more than one pair at a time with a couple of light items. Towels & washcloths are always laundered by themselves (never more than 2 or 3)... as are sheets & pillowcases (sheets, one a time).
Also, another note about the non-vented model: the way they dry clothes is to, believe it or not, use water... aka, steam. As such, after drying, the clothes are still slightly damp. Because of this, they need to be removed right after the drying cycle is complete (or just a few minutes before) or your clothes will be a wrinkled mess.
As I said, I travel alone... so the unit works well for me. And since I don't bring a lot of clothes with me on a typical trip, I usually end up tossing a load into it about every other night before going to bed. In the morning, I again run the load thru the drying cycle only during breakfast... and then remove, fold & hang the items afterwards.
