In the absence of a manhole type dump point you just pump through a one inch hose (you could use smaller but it doesn't flow so well) it into wherever everybody else is disposing in to. It's simple and remember you only need to empty infrequently as the tanks are quite big, every two weeks or so in our case. I looked at the Thor Aces a couple of years ago and thought them a pretty good van.
Some detail. A three inch flexible pipe goes from the waste outlet on the van to the pump (macerator 12v). That hose fixes in place by twisting on. The pump has a one inch outlet but you could reduce further. I'm currently parked 50m from the dump point here, it's a toilet bowl fitted outside and was intended for cassette emptying. The pump chops it up and sends it the 50m as a liquid and up into the toilet bowl easily, two or three minutes for 60 or 80 lt. I then shoot the contents of the grey tank through to clean the hoses. Finally I disconnect the one inch hose (twist connector)held high from the pump and walk to the dump point passing the hose backwards over my shoulder so the any residue goes into the dump point. I've done it into toilets in houses and never spilled a drop. It's just as smelly as cassette emptying except that you don't need to stand right beside it as you empty. I hope I've made myself clear.
Go for it is my advice.
