We have the combo unit. And I use it. It's easy to run a load sometime throughout the day. If we aren't heading right out in the morning I can knock out a load then. If not, if we are at the rv early in the evening, I'll run a load. I'd prefer the stackable but the combo is what came with our new rig. I am much happier doing our laundry in our machine rather than at a laundrymat. I don't have to pack as many clothes or linens. And it's great when we are in Florida to keep towels dry, sportsclothes washed up & swimsuits free of pool or ocean water. I'm glad to have it!
