I have the portable FloJet Macerator pump that attaches to the TT black/gray discharge hookup. I use it at home with a 75' 3/4" hose to empty and clean tanks following a trip. Hose attaches to an outside septic tank clean out. Works very well for that purpose.
I found that it was a bit noisy and took too long to use at a campsite, so I don't take it with me anymore. Emptying with the regular slinky is quiet and fast. Macerator would be advantageous, however, if you encounter a site with an uphill run for your sewer hose.
I installed a waterproof 12V receptacle on the TT just above the discharge hookup and a marine plug on the Macerator for convenience.
