Items placed on the roof or inside the box fall through it onto the ground. I tried placing some pallets and cones and stuff and it looks like it doesn't have collisions to items.
Would you consider doing a version of the service crane bed with the BetterWinch mod like the T880 truck? It's unfortunate being limited to only certain types of stuff like big bags.
But otherwise a superb pack! I also liked the nice touch of the Mtex logo on the Super Duty.
