sjrellis,
I'd better not do that without permission from AGI. I can summarize it though.
A Bighorn owner asked if one could replace the standard toilet in his Bighorn with a residential style, regular flush type toilet.
The column writer did not know whether the Bighorn owner meant to leave the unit on a site or travel with it frequently. The answer given was that you should not do it if you plan to travel with the trailer.
And if you plan to use it setup on a site for a long period, a caution was given to how much water a residential unit uses and the impact on the black water tank.
That was it.
