This mod lets you ingame open and close several crew hatches on both sides of the airframe.
Simply extract the zip in your Saved Games/DCS[version]/Liveries/CH-47F.
If you do not have the Liveries/CH-47F folder you need to create it.
While ingame, open the refuel/rearm window and choose an OPEN/CLOSED Hatch skin, but do NOT press ok. Instead press the X on the topright of the refuel/rearm window.
You can use this with every livery you want.
