Seems like a lot of work to avoid spending a few dollars at a private dump site. Depending on where you live there may be free public dump statons..
If you let the poop tank settle you could have problems when you dump later. Even if I only use my tank a few times over the weekend I will dump before I get home but first add water to black tank to promote a good flush, at least 3/4 full...
We have a septic tank located in the front yard. Since I get it pumped every 4-5 years, I dug out the clean-out and installed risers with a screw-on lid to make the job easier. This also serves as my own dump station at home. Works great.
