It's hard taking evidence like this seriously that is devoid of any facts and just relies on opinions.

Exactly. The "hostile environment of the moon's surface" was a vacuum, nothing else.
Here's the pressure vessel viewed toward the top of the vehicle, showing the docking hatch which connected to the Command Module, and the rectangular window for viewing the docking aid. The windows and hatch used for entry and exit on the Moon are hidden, and are to the top of the assembly.

Here's the view from the rear once most/all of the ancillary 'stuff' has been bolted onto the side of the pressure vessel. This includes various tanks, and the electrical/system panel (to the left in this photo). The CM hatch is to the top, and lunar hatch hidden to the right.

The ancillaries did not need to be pressurised, just needed a basic covering. There was no wind, weather, or other atmospherics to cope with.
