To dump the Sealand, you simply open the gate valve under the trailer. The same as the Thetford except you don't have the extra valve as part of the toilet or tank. I believe this method is how black tanks empty on other RVs, so it's nothing atypical.

According to the specs published in the manuals of both toilets, the Sealand is:

WIDTH: 1 7/8" wider (the tank portion) than the Thetford, so I'm not sure if there is extra width there or not, and my TM is all folded and covered. It will probably be close.

DEPTH: ~1/2" shallower

HEIGHT: roughly the same; the height of the Sealand is 2" shorter from the floor to the rim of the bowl, but that doesn't include the seat. So the Sealand isn't taller unless the seat sits more than 2" high off the bowl. But the top of the Thetford is several inches lower than the sink, so height shouldn't be an issue.
