We purchased a used 2018 silverback 37flk this spring. The previous owner just used it on the weekends and never had a washer booked up. We live in ours all summer and use the washer every day. We found out that the factory plumed the washer into the black holding tank as we have to drain it every 3 days. I just got off the phone with your customer service lady and she wouldn't take any responsibility for the screw up since I'm the second owner. I told her to explain to me why I have to pay for your company screw up, no good explanation and she eventually hung up on me. I have been self employed my entire career and this is unacceptable.
