The truck has no canopy. It has several states though:
Model: armies\soviet\vehicles\us6_truck\us6_truck
State machine name: us6_state
Values: base, katyusha, supply
State machine name: supplies_loaded
Values: empty, partial, half, majority, full
These states can be found with the worldbuilder (C:\Program Files (x86)\Steam\steamapps\common\Company of Heroes 2\WorldBuilder_CoH_2.exe)
This has a NIS function which can show a list of states for each model.
