Detroit Diesel 12V71 Add-on for Mack Superliner by Alpi0120 v1.0

Detroit Diesel 12V71 Add-on for Mack Superliner by Alpi0120 - I wanted to add a V12 2 stroke roaring engine to my favorite truck mod. I added Detroit Diesel 12v71 engine with 2 versions. All specs are same with real life specs. Engine sound belongs to Kriechbaum's V4.1. Addon Credit: Alpi0120 Truck Credit: 3D...
