After a few years and MANY requests, I started a build line of 4 blocks wide about 1.5:1 scale vehicles. I'm still building 5 blocks wide about 2:1 scale. I'll post the scale in the title and block count in the description. But you need to pay attention to the post, Make sure your downloading the correct scale build.

Been asked if I stopped building the larger 2:1 scale vehicles. My reply was NO, helping a city server. In need of some good 1.5:1 scale vehicles.

The Mack DM series was a line of heavy-duty trucks, The DM was a heavy duty "U", The "U" was short hood, Offset cab. The “U” and “DM” series were modifications of the “R” series. A short hood, and the shorter “bumper to back of cab” distance, made them useful in straight trucks and in semi-tractors used in congested cities, but caused the engine to intrude into the passenger compartment. To compensate the cab was offset to the left: the engine “doghouse” intruded into the passenger footwell but left the driver’s position intact.
The U was basically a short R, while the DM was an extra heavy duty version often used in 6X4 construction trucks. Like the RMM, the DMM was all wheel drive, but had not only a short hood/offset cab, but also a set back front axle, requiring a model specific fiberglass hood/fender arrangement
