I always said if someone made a large nonslide camper I might be interested. I see a 12fter on Northstars site that looked pretty good until it showed a 4.5 gal cassette toilet that I know nothing abo...
We have the Northstar 12' STC with the cassette and are extremely happy with both. We visited Rex, the owner, at his factory in Iowa last year. Very impressed by construction methods, support, company philosophy, and most of the materials.
The cassette makes "dumping" easier with many more options. I have briefly thought about getting a backup cassette holding container for when we are away from any type of dump opportunity with 4 folks using the toilet...but they are kinda expensive.
