On our Rockwood 23WS there was plenty of room to add a 2nd 43 gallon freshwater tank, and where the black and gray tanks are located they both could of easily been doubled in size from the current 39 gallon size, but is a little harder to accomplish after the fact unless I wanted to basically reconfigure all the plumbing which would of probably required tearing into some of the inside construction. The tanks go in first prior to the rest of the build so its problematic to change. There are plenty of other models / floorplans with the same box size made by both Forest River and other manufacturers with much smaller tanks. Its determined more by manufacturing costs than size IMO.
But Ralph ... is your Rockwood 23WS chassis enough overkill to handle the additional weight of those much larger tanks?
A gripe of mine regarding many/most small RVs is that their frames/chassis is just barely rugged enough for the weight of the RV itself ... with not a lot of headroom for the weight of users's camping stuff ... let alone larger tanks.
We intentionally shopped for - and eventually found after a year - a small RV on an overkill chassis. We can travel with all tanks full if we want, plus gobs of camping gear, plus rocks (we'er rockhounds), plus more water if we wanted to add another tank. But this combination is almost impossible to find nowadays. Construction is usually adequate - but not more than adequate if you want it.
