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. Quote Matt Link to comment Share on other sites More sharing options...
whitegold Posted November 11, 2013 Author Share Posted November 11, 2013 okay, is there anything different about a western truck? Quote THE MILKMAN DID IT..... Link to comment Share on other sites More sharing options...
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. Quote Matt Link to comment Share on other sites More sharing options...
