I sure hope yours went easier than mine. Typically this might be an hourish job?...
Toilet arrived-setting on floor its a tad wider. We have a raised section of floor, positioning so toilet didn't hang off edge
meant I couldn't scootch it over as I hoped to cover more of the misplaced hole in floor.

Ended up gluing in dowels and redrilling floor. Also used some foam backer rod to hold sealant
(should have cut block arc a bit larger).

Bedding the flange in sealant just seemed wrong, but necessary...Bed the flange, screwed it down then applied half a
tube of GE silicone II to face and edge. Set the toilet and with my weight on it tightened it down. Took a while and more
force than I would have liked to compress that foam gasket. But NO ROCK!
Cut off the previously hard plumbed PEX and installed Flair-It valve with flex line. Later when I get a restraining hoop
like used on shower hose Ill recut and place valve closer to wall. Or just hoop where its at.

Nice, what can you say -toilet. The added height easy as is the foot control. Jury's still out on the textured lid-I can't
touch it, doesn't clean easily? The valve will be nice to throttle water volume. Thetford recommends rateing at 10
quarts a minute? More for saving water and tank capacity when camping but recently stayed a few days in San Juan
Bautista (BBQ cook off). CG city water and it filled the black tank in 2 days-cutting in half or so should cut water use
and storage.
Left to do is cut my rinse wand and extend...
Got everything put away and cleaned up last night, reflecting on our new toilet, picture of the tape dam I used to seal
pipe popped into my head. Ummm...Yep... I hadnt removed, looking in toilet its floating in tank... Oh joy
EDIT:
rinse wand extended

With little hope, rinsed black tank into blue auxiliary bucket..drained using 3/4" garden hose. Wanted to verify if tape dam came out.

Amazingly came out first try. Assumed would take several tries, if at all. All's well that ends well...
