Bongo Fury

Hi, we’ve just bought a Bongo in NZ with a basic rear kitchen, that we want to convert to meet the NZ self containment standard. To do this we need to vent the internal waste and fresh water tanks outside. I’m assuming this could be through the floor, rear arches or rear bumper, but not sure where the best place is to do this. Are there good places with existing holes or do I need to cut some, if so,where. It can be on either side, or even in the middle. Many thanks, as we are new to this and haven’t started dismantling anything yet!

I don't think anyone has reported finding any desirable holes (a few rust ones maybe ) so its really a case of finding a blank spot and reaching it internally. Externally keep away from the spare wheel area also any towbar fittings and make sure its reasonably accessible I guess!
