Here is one example of towed artillery. Truck and gun are single object.



Parts are not properly aligned but this is just a quick demo.

No properly aligned, does that mean you can get them closer together?

Yes. What you see is just a 5 minutes work, I only wanted to demonstrate the concept. There are 4 parts there. Truck is single mesh object but gun have three meshes and you can move all of these parts to desired locations.
