I'm guessing a one way valve would prevent a backlash. You should be
able to adapt it for pump out. It'll take some dismantling, and
rigging the piping, as well as drilling the deck to accept the plug.

it looks like everything is in place, including the connection to the
toilet. the only thing missing is the sanitary line from the head to
the pump out connection on the deck. i just want to make sure i don't
blow up the toilet when i flush it out.

You worry too much. Go for it. What's the worst that can happen?

yeah. you suck a vacuum on a container not designed for it...and then
backfill it with water...the results would be unpleasant

If you plan to do that, you deserve to have it blow up in your face.

Is there a working vent in the holding tank? If you play your cards
right, the only vacuum applied to your system will be in the suction
hose that connects to the deck plate. I'm not sure what you mean by
backfill. You don't mean rinse, do you?

I had a small MSD on my trailerable Sandpiper 565.
It had a deck cleanout and a vent. i never did use it but it was typical of
what was installed on boats in central Canada in the 80's & 90's.
Here on the coast we are still allowed to discharge directly to the sea.
