Gavril MD-Series

That's the lightbar controls. You need a lightbar mounted to mess around with it. I guess the armored truck came with it by default so it had a CB radio in the cab.

Armoured truck config paints seem to have changed with this hotfix. The Moneygrab is full red, and the SWAT van is now white. Was the SWAT livery planned to be paintable? I've noticed when changing the secondary vehicle paint that the text shifts colours very slightly.

 

it is missing the rollback on it i would love to have a tow truck version of the truck

 

I don't have the same problem? The moneygrab for me is still red with a black hood (it's colorable). And the SWAT truck is colorable as well - it has been from the start (unless you're talking about an H series config then I don't know cause I don't pay attention to that car)

 

Speaking of which, it also seems like these color options below went missing from the MD-Series in general after the current hotfix if I'm not mistaken. Some of them were even on the Derby Bus configurations too.

Taxi Yellow
Toxic Green
Cactus Green
Shale Green
Shadow Blue
Steel Gray
Matte Orange
Matte Lime
Matte Pink
Matte Gray
Matte Mid Gray
Matte Dark Gray
Matte Black

 

Odd. Maybe some mod is interfering with it.
