Up until a couple of years ago, my personal library included an owner's manual for a '72 or '73 Airstream...in it was described an optional sewage system that looked pretty complicated.
If I remember correctly, the trailer had a macerating pump that drew from the black tank. When you hitched up to your tow, you had an extra line (sewage) to hook up.
Once underway, the trailer would pump the (now liquid) sewage to a contraption fitted to your car's exhaust system, using that as a heat source to burn it away.
I forget what the final form of the waste was (ash?) and what ultimately became of it.
My Dad says he vaguely remembers this option and doesn't think they sold many. None of his Airstreams over the years had it.
I wonder if it actually worked for anybody who had it.
I'm pretty sure you could also just dump the tanks in the conventional manner on the trailers with this system.
Anybody remember any more info about this?
ps I don't have a slogan for the Incinolet, but how about a song for a TV ad?
