we have 116 fresh. The trailer had 38 black and 43 grey, the 4 of us would fill the grey in 1.5-2 days. The trailer has 2 fresh tanks, I moved one back and added another 36g grey, total 79 now. It's the best thing ever, 4 days no problems. The bath sink goes into black so we do all hand washing there. The weight distribution is sort of a crock of sh*t, there isn't any difference towing. My water starts out mid ship, that gets transferred to the front for 20-40 miles until I dump then there isn't any weight, I don't notice any difference.
