Steve,
Welcome to the Stovebolt. I have no clue what year your new treasure might be, but the truck sure is interesting looking.
With all the winches and weird wrap around platform, it almost looks like it could have been some sort of well drilling rig.
Could long sections of drill pipe have been stacked on each side of the cab? If the truck is indigenous to the Sacramento valley area, maybe it was used to drill wells for the farms.
