The best is if you have room for a stackable. I didn't want to sacrifice that much room. I have a Splendide combo with ventless drying. Disadvantage-it takes at least an hour to dry, uses more water (it uses cold water to wash the condensation off the warm drum) and the clothes never really dry-which means hanging them up for another hour.
In my truck I'm still going with the Splendide all in one, but with vent. It is the only combo I know of that has vented drying. Good Luck, TomC
