Spent some time in Brazil, and everyone there throws their TP in a waste basket next to the toilet. Their septic tanks mostly consisted of round cesspools, with brick laid on edge. No drain field. The wastewater leached out the holes in brick so TP (and other inorganics) would clog the holes and prevent draining. The cities had wastewater treatment facilities, but people still put their TP in trash cans, presumably because of the cultural practices.
My business is in the water and wastewater treatment industry. There is not a working wastewater plant in the USA that cannot handle TP. Baby wipes are a different story. If you are connected to a municipal sewer line, there's no reason you should not be flushing TP.
As for RV's, here's another vote for doing #2 and using regular TP. Sure, you might get a wad that gets hung up in there from time to time, but as long as mostly everything drains out, your OK. Just put some waste treatment stuff in there and get the remnants next time. I don't care about the sensors...you don't have sensors on your septic tank, and just like your holding tank, you'll know when it's full.
