How long until your holding tanks are full?

WE used our new MH for the first time, 2 weeks ago. When we bought it the indicator showed that the black water tank was half full (or half empty depending on your mood). So I dumped it in the morning. 24 hours later the tank was completely full to the point where you could not flush again. That seemed real fast to me. In the past we had gone boondocking in our old RV and the tanks lasted 4 people a full weekend. How long does it take you to fill up your tanks and how many people are with you when you are using it?

It is highly unlikely that it would be possible to fill a black tank in 24 hours unless you have many, many folks on board and you were drinking a lot of beer! One possibility is that you have a leak in the toilet but that would have to be a leaking valve going in and the tank itself leaking out (unlikely).
It would be more likely that when you dumped you did not get a good dump. That could mean a clog, a "pyramid" or some similar issue.
As mentioned above, what RV is this, but I can't think of any RV that would fill a black tank in 24 hours of normal use.
