connecting grey tanks to get more capacity for the shower

We're looking at the Grand Design Momentum 328m which has two separate 52 gallon grey tanks, one for the shower and another for the sink. It has 160 gal of fresh water. We're likely to use much more...

You can use a twist on valve at the main drain exit, if both gray tanks empty from there. You can just open both tank valves then to make one big gray tank.

X2 ^^. This is what we've done with our GD Reflection. There are quite a few posts about this over on the Grand Design Owners' Forum.

P.S. - NEVER cross-contaminate your black and gray tanks.
