eliminating the black tank

Is it possible to eliminate the black water tank in a 1976 Overlander and run a line directly from the toilet to the outside (to the a septic tank or disposal site)?

It's possible but not a good idea.

The blackwater tank helps liquify the #2 by mixing it with the #1 and water. When you open the valve, the whole liquid mess flows out rather nicely.

If you eliminate the tank, the "solids" will stick to the piping and you will have a clogged up mess.

If your tank is leaking and you want to eliminate it, get a regular house style toilet. They have a water tank that provides enough liquid to get the whole business flowing. They also have a trap to seal off odors. Even in Arkansas you should freeze proof any above ground pipes.

Great reply Markdoane,

My sentiments exactly! In Florida, a favorite routine for folks permanantly living in an RV (usually a 5th wheel) is to buy a lot in an RV park, strap the RV down to the concrete pad and then install semi-permanent PVC water and drain lines with a domestic type toilet.

Without the full-flush ability of the domestic's tank, it is difficult to get all of the solids down the drain pipe.

No a good idea. You need the holding tank even when parked. Just letting it run out will let the liguid leave and most of the solids stay behind.
