Just bought a top gun and have never used the bathroom in it.....what steps do i need to follow to use it and when do i know when the **** tank is full????

In the front under the right side coushin are two valves. One is larger than the other.

Flip the smaller one on - that is incoming water that will flow into the toilet when you run the pump. There are two buttons. One that isn't labeled on the left and one that says "push to flush" on the right.

Use the one that says "push to flush" to flush the toilet after you piss.

To empty it either have it pumped out, or go back under that front coushin, flip the Larger of the two valves, and push the button that isn't labeled - that will flush it overboard.

It is only a 6 gallon tank. What we do sometimes (since only my wife and I use it) is just piss in it with the incoming water turned off and then flush it, washing it down occasionally with some fresh water. That way it fills up slower.

You'll know when it is full because it will quit flushing......
