What is a loaded truck? The unit of type TRUCKB? Or a unit defined like this:
[TANK] ; your unit type here
CarriesCrate=yes
IsTrain=yes/no
And in the scenario/map:
[Basic]
TruckCrate=yes ; if IsTrain=no
TrainCrate=yes ; if IsTrain=yes
Also, are crates enabled in the skirmish menu? If not, please enable them, and start a match, even if you have this crate problem in missions. if that generates a crate and with the crate option turned off in the skirmish menu doesn't, it might be the same problem as the disabled super weapons in campaigns.
