Thanks for an interesting review.
They do look good.
Your point about the doors is telling, though I thought armour packages for HMMWVs came after the invasion of Iraq (proper ones replacing the "hillbilly" armour even later).
The other interesting thing is there is no option for the skeleton version, from my memory of Evan Wright's book (and the mini series) (so YMMV) the US 1st Reconnaissance battalion used HMMWVs without doors.
