There's a lot of variables. How often are you going to shower and do dishes? How big are the tanks? Do you take "Navy Showers"? How good are you at conserving water? I camp alone, shower daily and try to keep water usage down and I empty my tanks about once a week. When I camped with my wife, we had to dump the tanks every other day.
Agree with this whole heartedly.....When we had our TT, it had a much larger gray tank than our Class C. 3 of us not trying to be frugal with consumption (3 showers a day and some light dish washing), we would need to dump at least every other day. With the Class C and tank about 2/3rd the size of the one in the TT, we can now go about twice as long, but we learned to be more frugal with the water. Changed the shower head out...turn on water and get wet. Turn off and lather up. Turn on water and rinse. Done. WE could probably be more frugal and get another day out of it, but we haven't needed to. If you have a bath house available that you are willing to use, then that will help a lot. Especially with kids. Then you can take long hot showers if you want.
On another note, don't think all Class A's or Class C's will have the same size tanks. There are Class C's that are smaller than ours ,but have bigger tanks. Class A's generally will probably have larger tanks than a Class C.
