2stacksuperdog Posted November 11, 2013 Share Posted November 11, 2013 RW713 is a heavy duty RW313. a RWS would be a western truck. a 12 is shifted 1 D, 1H, 2D, 2H, 3D, 3H, etc up to fifth gear. Its a 10 speed with low gears pretty much.

2stacksuperdog Posted November 11, 2013 Share Posted November 11, 2013 Usually western trucks have a lot of aluminum components to make them lighter to comply with the stupid California regulations. I'm sure there are some on here who can give you a exact breakdown in differences.
