I'm almost to the phase in my renovation where i will be adding the combo black/grey tank and accompanying plumbing. My plan is to have a kitchen and bathroom sink and a toilet, but no shower. I'm planning on using a 20 gallon freshwater tank, and 40 gallon combo black/grey tank.
I know that the toilet needs to be mounted directly above the black/grey tank, which has been accounted for in my floor-plan. I was going to purchase this tank:

My questions and concerns revolve around the plumbing connections from the toilet to the black/grey tank:
Do i need to have the 3" inlet location on the black tank pre-measured and pre-installed by the factory, or can i just use a hole saw and cut out the location
after i mount the tank on the underside of the bus? (same for the grey water 2" inlet?) If i go the route of using a hole saw to cut out the 3" inlet location, what kind of flange or gromet would i need to make sure the connections are tight? Can any of the veterans out there point me in the right direction on the correct way to go about this? What about which parts or install kits i need to purchase? I know that i'll need an RV toilet floor flange, but what else?
Also, I purchased a Dometic 310 ReVolution Toilet and am a little nervous about how to actually get the plumbing connections to line up so there is no leakage (ewwwww). Has anyone installed this particular toilet before? Any advice to avoid a messy and smelly mess from faulty installation?
Thanks in advance for any advice you might be able to offer.
