Add rosenbauer commander mid mount pumper

[Michael_live_earth]

I suggest adding a standard Rosenbauer fire pumper. Rosenbauer makes some of the most advanced and efficient fire trucks in the world. Here, I suggest adding their standard fire engine, also called a pumper fire truck, based on the Rosenbauer Commander chassis with a mid-mount configuration.

We currently only have two fire trucks in the game, and both are premium, and neither is a standard US fire engine. Additionally, we already have a fire station in town, so this would improve firefighter roleplay and diversify it.

Basic info:

Chassis: 4x2

Manufacturer: Rosenbauer

Default color: Red

Variant: Mid-mount fire pumper

Engine: Cummins X15 diesel engine
