Bathtub backup

I have a question....we are new to this. We must purchase me a used 2006 Jayco Jayfeather 26l. We are definitely still learning. We have Ben out about 4 times since making this purchase. On our last trip our bathtub backed up. It did not overflow out of the tub, however we had water coming from somewhere on the floor. Like underneath the sink cabinet. Can anyone explain why or how this may have happened?

It makes me nervous possibly having water leaking problems.

I know it was full. My hubby did a not to smart move and let the sink run to fill the grey water tank so when we emptied the black water tank there would be enough water to rinse out the black water drain pipe. My question though is where did the water in the floor come from? Is there a leak in a pipe or the tank???

The drains go directly into the grey tank so when its over full it backs up to where ever it can escape.

There may be a vent in the cabinet under the sink ( don't remember exact nomenclature ) that is not functioning properly. Theoretically it's not supposed to let water out, just air in.

It's not necessary to have a full grey water tank to flush the lines after dumping the black tank, several gallons will do. Then be sure to put a few gallons of fresh water in the black tank after DW drains it. Never want to leave it empty. You may or may not want to add some soap or toilet chemical then, too.
