According to the article, the system only pumps waste into the exhaust when the exhaust temperature is 900F and the vehicle is moving at least 35mph. So just dumping sewage onto the streets isn't how they work at all, unlike they're broken I guess. Also, this system apparently wasn't common, since it was just on one model, in one year, right before the oil embargo caused the entire RV industry to mostly die out for a while.
Honestly, this thing doesn't sound like a bad idea at all. It would be interesting to see how it really affects tailpipe emissions with some modern testing (when it's working properly, of course).
