modular gun truck

a flat bed gun truck idea I had where you could swap out different kinds of weapons turrets on the back. I've only made a MG ball turret and an AA missile turret so far. Was thinking of adding a flame thrower turret or maybe something like the old duel 40mm bofors AA guns from WW2 era. Its made so the wheels will turn but I wouldn't expect this thing to roll freely very well.

update added the twin bofors AA turret
