Single post to hold up a 14-ft gate is big task even if the gate is
fairly lightweight one.

Probably only way your're going to do that is to dig a much bigger hole
for larger cross-sectional area perpendicular to fence line to brace
against.

The typical way is crossbrace or deadman but if no room for either, then
more beef in the hole against the bearing surface is about only
choice/alternative.

Or, there's the other expedient of running verticals on both sides with
stiff member between and translate the load to the length on the other
side of the opening.

It sounds like his giant gate needs to be on wheels to support the
load.
