Hi Guys
Now for the difference in Reverse
As you can see in the middle picture above there is about an inch more clearance in side the box with transmission in reverse.
As the plug is located in a position almost impossible to actually look in on the truck, I remove the plug an insert a finger (clean of course) and crock the first joint to check the level.
Now for curiosity here is the top cover with all the forks set for Neutral I have a copy of this picture and one looking down into the transmission with all the gears in the neutral position as reference in the shop.
The last picture is transmission tick tac toe for where are the different forks positioned for what gear.
Note of explanation: The reason for all the grease on the gears, this is my spare transmission that have repaired after breaking a tooth. As this one is in storage want to really protect it from rust so I coated everything inside in a heavy layer of grease. Then sealed all the opening as much as possible.

Now for you Ford guys is there one gear better than another for checking the lube?
To sum up
What gear should you put a Chevy CMP to check the lube level in the transmission?
Answer
Reverse as this moves the gear closest to the lube fill plug away by an inch. Allowing for easier checking and easier adding of lube if needed.
Side point don't over fill it just makes them leak more.
