Wow, this is great discussion, I really appreciate all of the feedback.
The Northstar we are looking at is a 2020, they have changed the windows this year or last to a different manufacturer. Also, they finally updated the colour on the cabinets to something a little more progressive. I do think that Cirrus and Bunduvry are the only manufacturers who are innovating in camper design. Along with some of the very high end expedition ones that are way beyond my budget.
I guess, for me, since our current camper has no bathroom, anything that means I don't have to get out of the warm camper in the middle of winter in the middle of night to have a pee is a bonus. Going to a dump station with a black hose I've done years ago and it was tolerable but think for us, since we will be camping 99% of the time without hookups, the cassette is a better fit. Often the dumps are closed in winter, and the outlet valve would freeze.
I am going to make an offer on the Cirrus 720 and see what happens. Alternatively, there is an 820 that the dealer has already come down on, but I still feel like it's pushing the weight on our truck, and then I am back to the black tank scenario.
Stay tuned, I might be in a new camper soon!!
