For some odd reason my game crashes when trying to enter both the Sandstorm and the Cavalcade. I've tried getting into other mod vehicles and they've worked just fine, is there anything I'm doing wrong or?

I'm just having a quick question for ya, how exactly do you put the Steelies on the cars? thanks in advance!

Causes my game to crash when I try to spawn it in, any pointers? I have the PFLA and the Heap adjuster installed already

I can't seem to get it to spawn in, I have the ADD On it is not showing in my ADDON vehicle's menu

What is that black stuff in front of the wheels?

Is it actually the truck or just the handling and stuff?
