Electra San Waste System Pro's and Cons

Well two of you say I am trying to solve a problem that just doesn't exist. And maybe it doesn't exist for those who stay in organized campgrounds. Well ok lets say an rv'er is like me and doesn't stay in organized campgrounds but actually camps outs in the brush or maybe the desert. Now when our waste tank gets full we find it necessary to pick up and drive to a town or maybe a interstate where there is a dumpsite. Thats no little task packing up all your gear and coming down mountain roads or across twenty miles of desert sands.
But if we didn't have to leave every 4th or fifth day to dump sewage it would be much better.
Just a thought. Now maybe someone can pick holes in that thought.
