I doubt those M1084s ( 4 of them out of Ohio) were War Pigs in the sense they would had probably been used to resupply outlaying outposts/communities, utilizing the crane to offload palatalized supplies quickly.
The cab of those truck were cutoff ( nothing to think they’re a LVAD cab) and sheetmetal was added along with the cage which probably had a M2, instead of in the bed to facilitate maximum load.
During the time ( over 3 years ago) I was fitting my M1094 to replicate a War Pig, the pictures and info I had been able to find indicated a War Pig was the resupply and command/communication vehicle for long range patrols. They were all hand stocked to have ready access to all supplies.
Just my opinion, but logically, I don’t see the modified M1084 in a resupply role for a convoy with a crane that adds a bunch of weight to the truck and another 32” of length.
Working with a SF group to take palatalize supplies to an outreaching community or base, yes.
I could be wrong… it wouldn’t be the first time, and logic doesn’t always apply
Oh, BTW , several pics on GP show some hard contacts (bends) to the drive shafts on a couple of the M1084s
Plus none of the lights were sprayed or taped over that was common to the warpigs.
