Sorry, I know this is a sore subject but I feel compelled to reply in greater detail to FreightTrain's comment.
I mod my trucks. There, I said it. Do I think that folks who restore or keep trucks original are morons? Of course not, I love seeing original machinery but if you think that all equipment, cars, machines and mil vehicles should be kept original that is your opinion but it does not make you a moron in my eyes. I do think that is a very short sighted and myopic view if you believe that ALL things should be kept original, after all it is the ingenuity of the owner to mod their truck as they want it to be. If we did not have that creativity then these great vehicles would have never been created in the first place!
I agree with Bruce in that his mods are limited to military approved things when desiring to keep his trucks "original", but even then ANY change, whether it be approved or not deviates from how the truck was when it was delivered to the military. This means that it is no longer original and you have modified it. Do you think that a COPO Camaro on Barret's would fetch top dollar if a guy decided to put a different rear under the car even though GM made it and it was actually in some Camaros? No, even if one thing is changed it is no longer original.
So you see, there are varying degrees of modification from bolt on military parts to bobbing which for the record I think is cool looking but I would never do. Why? Because it exceeds what I deem acceptable for a mil-vehicle mod but I do not think that it makes the owner a moron. That kind of comment can generate a lot of animosity and I understand that you are not actually calling folks out, just saying that you have the right.
I like modding my trucks, but I also try to keep the look of the truck "original", kind of like an experimental model sent to Uncle Sam for evaluation.
There are two camps here, modders and non-modders. As different as water and dust and it will never be reconciled but let's try to appreciate everyone's ideas and beliefs with these trucks because together our voice is strong!
And if I have not interpreted you correctly FreighTrain, I apologize in advance.
