Yes we are leaning toward having the 1/2 bath as a plus with two girls plus a friend once in awhile. Just will have to buy some additional sewer lines and some fittings.

You know I have all those connections. I've decided that it is easier to just move the hose from the front connection to the rear connections vs. getting out all the hoses and connections.

I'm basically a weekend warrior.
We're never going to fill the black tank on an average outing. We dump gray as needed.
If I were full timing or did more week long trips then using the 2nd 1/2 bath would be more worthwhile. But for a 2-3 day weekend I see no point in have 2-1/4 full black tanks.
I understand I'm in the minority on this, but the additional dumping is a deal breaker for me.
