Bill:
We agree with azstar. That is why we had it added as an option. We thought that with the grand kids it would prove to be a wise decision. As yet, we haven't used it, but as new Rvers, we haven't used our unit enough last year to know if this a fact yet. It could be beneficial in washing off hands after fishing also. Potentially, it could have been a good decision. Good luck with your decision. We also chose the 3400rl as our unit.
