You can install all the interior items to the floor with just bolts and
nuts. I have done so several times. I use locknuts so they don't have to
be tightened to the point that anything is deformed. I don't use the
stock under cabinet floor pieces but cut my own from luan, a soft thin
plywood. The rear bed hinge strap screws can be done with nuts too, even
the one you think is blocked by the Syncro tank, that isn't really blocked.

The metal of the passenger van floor has small factory dimples marking
the center of the holes needed by the water tank, etc. They don't look
very obvious until you lay the original floor pieces inside a passenger
van and then they jump out at you. I use holes saws, started in the dimples.
