Alright! I think I've finished the model to my liking! However, I figured out that I'm quite terrible at making circles in blender, so I'm showing it with the crash tender wheels by Hoppah in the LA mod. And all the emergency lighting has been added as childs, I did this so that when people use it, they'll be forced to add their own lighting and we'll be able to see some variety, and I did not make any of the emergency lighting either, credit goes to EmC-unit for that.
So this is it! Any last recommendations of anything I should add? And I've added a poll in the thread, please vote on what unit I should make next!
