Using the tank rinse takes a little extra time,, I usually hook my own hose up to it and let it run for a few minutes to agitate things a little and add some more water into the black tank.
I keep it running while dumping the black, when black is no longer at full flow, I'll close it and open the grey tank,keeping the rinse in the black going.
When that stops I allow the black a little more fill time, then get a good flush rinse out of that. Now I allow about five to ten gallons flow into the black for the ride home.
I disconnect my water hose then use their hose to wash my stuff off!!
Dump time varies but mostly ten or so minutes to complete the job!!
Never have had anyone blow a cork on my flush time, matter of fact I have met some really nice folks, Last time a nice older couple next in line got out and struck up conversation with me during the process and liked my drain hose storage, they even snapped a few pictures of my set up!
Maybe its the end of the continent that makes this a slam bam rush angry job??
Some things just shouldn't be rushed!
