While I am gutting out the '84 Starcraft I was given and restoring it, I was really hoping to add some type of toilet. We have 3 children (4, 6, and 8) and the 6 year old still has issues with wetting the bed. Having to shuttle the children to and from the nearest toilet late at night and at the break of dawn is no fun at all. Naturally they never all go at the same time either. I would like to add an RV flush toilet. Has anyone ever set one of these up to dump directly into a portable waste tank? The regular waste tanks that mount under the camper are very expensive and I don't have much ground clearance under the camper. You can get a much larger portable waste tank for the same price as a regular one and it could be stowed away somewhere for transport. If I rolled one of the portable ones under the camper so the hose goes straight down into it (or at least close to straight down) from the toilet, would waste flow through it alright? I am not proposing having the portable tank 20' off to the side or anything. My main concern is that waste would get caught in the hose and that disconnecting it to dump might be a bit messy with this setup. Any opinions would be greatly appreciated.
