I just came across this 1944 Mack fire truck which debuted at SEMA 2011. The truck is owned by Roger Brown and was built by his friend Tom Start of Precision Designs. The truck is called “Black Dragon” and features a 2005 Viper SRT10 V10 and Dodge 48RE automatic transmission. The front suspension is stock but the back is from a 2008 Ram truck and the brakes are from a Ram SRT10. Those are 24 inch wheels in case you are wondering.
