vaguely proposed a theory

Just abit late maybe. But The bilge pump will struggle to fill that
tank. Give it a go, but it will be at best way under rated flow. They
are meant to work at 3-4' of water head.

O.k. got an argument to solve.

Have a 55 gal. barrel, on a 8 to 10 foot tall platform (to provide water
in deer camp).

It has three bungs. One on the bottom side (drain/flow). Two on the top
side. One for vent, one for fill.

There is another barrel in the bed of a pickup, full of water. There are
two pumps, one hand diaphragm type or one typical 12v bilge type. This
is the source of water to fill the high barrel.

The argument is that the water can be just as easily pumped into the
barrel through the drain bung, from below, as it could be through the
top fill bung. There is an assertion that the pressure inside the hose
is greater in the lower fill hose than in the upper fill hose, due to
the weight of the water in the barrel as it fills.

Which, if any, fill location would require more or less force to fill
this barrel: the top hole or the bottom hole?
