If you hang things on the mdf door, sooner or later it will twist and
close at the bottom, but not at the top.

Not sure if any door will be imune to lop sided weight in the way you
describe.

A very rigid one obviously would be.

I need to make a cupboard door. Size is 990mm x 915mm with a maximum
thickness of 37mm. It will be to replace two existing hollow doors on a
large bedroom cupboard. The idea in having a single door is so that a TV
can be mounted on it.
The door fits into a conventional door frame as installed by the builders
so is flush with the front of the frame.

Initially I thought about making a hollow door with lap joints at the
corners and a vertical rib to take the TV mount and then cover it with MDF
which will be painted. Then I wondered if I was over complicating things
and I should just use a sheet of 18mm MDF. MDF would be about 12Kg and
the TV about 5Kg so heavy but not massively so. The problem with this
solution would be the hinges - I don't like the idea of screwing into the
edge of the MDF. Googling shows that other people either do it without a
problem or set dowels into the edge and then screw into these. So anyone
have any thoughts?
