dumping portable toilet contents
i was wondering what others thought about doing this ?
i have a portable airtight factory camper toilet that has a place to put in the fresh flushing water and the storage tank below .
which is what my stealth van will have one thought is dumping it in a gas station bathroom being careful not to make a mess and flushing their toilet .
i have done this in our own toilet at home after a stealth van trip to illinois .
I guess one could pay at a gas station that has a dumping area for r.v's
any other idea's ??
