what is the difference between dodge d100 and w100?
D100 is a 1/2 ton 2-wheel drive truck. Later there was a heavier 1/2 ton called D150 or W150. W was the letter designated to 4-wheel drive trucks. W100 would be a 1/2 ton 4-wheel drive truck but if it was built 68 or earlier it would have 3/4 ton axles with a short bed.
