I am not worried about placing actual troop minis in the back of any truck. Canvas tilt in place, and I am good. The truck will stop at some point, and my individually based minis will disembark and head into action. All is well.
I have a hard enough time building and painging minis I am going to fight with. Buying and modelling and painting passengers is way down my list.
So I want the troop transport because its the right vehicle. If it comes with a full cover in back, that makes it perfect.
If/when anybody ever releases passengers that fit nicely, I might think about getting those. I got the resin ones Warlord did for their halftracks on a whim. They are still unpainted. And I bought their Opel Blitz because it came with German troops for the back. Those guys are also still unpainted.
Anyway, as cool as the cargo truck looks, it is a pass for me. Hope it works for others. Hate for it to not sell, and that kills plans to eventually release the troop version!
