We bought a 2014 Axis 24.1. I'm a total newb and the more I read the supplied manual, the more questions I have (instead of less!) Things like: Do I have the Black Water Tank Flushing system? Should I spend time looking for it if I'm not even sure it exists? I'd LOVE to drain the plumbing-WHERE are the "Low-point" ports (plugs?)? "Re-fill the black water tank until the bottom is covered"-and you can tell that-HOW? Guess? (recovering sense of humor). Anyway I'd sure pay PLENTY for a model specific manual. Paid a little too much to trust this thing to trial and error.
