We're one step closer to possibly getting a Tab 400 BD in the coming weeks (RV loan pre-approved through our CU) and something we're curious about.
The 400 apparently doesn't have a cassette toilet? One of the things we like from what we've read (being first time RV owners soon) is that a cassette toilet means you don't have a blackwater tank to drain, just the cassette, which I would think would simplify winterizing the RV as well as not having to worry about having to pull the RV to a dump station if you fill the blackwater tank (just pull the cassette, walk to the nearest restroom or the dump station, dump, and return.)
Although, we did notice even the models with cassette toilets (320) have a blackwater tank, so the other question would be, what drains into that?
