MTL Haulking, a modern semi truck, is ready to take undisputed ownership of Liberty City roads. Unlike R* usual kitbash truck designs, the Haulking stands apart with its original assets. It was modelled by Calvin.linardi for GTA V, and my job was to optimize and convert it to GTA IV. 
Haulking comes in two distinct configurations:
1. Raised roof variant that features side skirts, a painted visor and can sometimes spawn with cabin extensions.
2. Flat roof variant with no side skirts and a chrome visor.
These variants work as extras within one model. It also has a chance to spawn with a mudflap bitch on the rear bumper. Truck features liveries with company logos and USDOT numbers. Secondary color applies to the side skirts and the visor. An adapted model for the LibertyCityPlates mod is also available.

Update 1.1 changelog (26.07.25):
- Fixed missing geometry on flat roof variant
- Visor was made slightly brighter
- Fixed flat roof livery UV mapping
- Fixed plate frame UV mapping
- Minor LOD improvements
