Inspired by several snow plows both in service and units seen at the Peterbilt Denton factory - my build is based on 2008-2010 built units. I scratchbuilt the spreader body, sander, belly blade, 367 SBFA hood (cast for me by AITM), KFS front wheels, Mo'Luminum rear wheels, Klaus Clever lights and I think the front drive axle was KFS but I can't recall.
The weathering is a combination of several products including Vallejo Pigments and Tamiya Snow (thank's to Brandon for suggesting these).
This build isn't finished yet (3/14/24) but I needed to take some photos to see how the weathering and snow looked so here it is.
