setting the toilet is the first step in the entire layout of your bus.
you can have a combination grey/black tank. back in the day, gray water was allowed to be disposed of on the ground. not so now. familiarity of the 2 tank system just stuck. i have a single waste tank on my bus, and i only dump at waste dumps.
the toilet is going to go where ever you can have a straight drop to the tank, as close to the tank outlet as you can. solids don't want to move very far, best to have lots of liquid behind it. the tank outlet is going to be where you make room for it.
my waste tank holder is made from angle iron. others use struts and threaded rods to hang them.
most waste dumps are set to have the valve on driver side rear. i put mine on the passenger side, so i have to drive through waste dumps backwards. usually easy enough except sunday morning when everyone is leaving a campground.
figure out what size space you'll have, where you want to mount the tank and get the biggest one that will fit. best to have about 20-30% more waste capacity than your water holding capacity.
find the spot for the tank, remove what you need to, get the biggest tank you can get under there, locate the toilet inside, and build the rest of the inside around that.
good luck!
