Three way tailgates are nice, but they do add alot of weight. I assume your talking about one that dumps regularly and swings open like a barn door. Im not sure if you can get the tail gate to tip open as well like a pickup because of the weight of everything and the fact that you wouldnt need it. I know Dominick at Transtar in Tukesberry (spelling?) builds a mean body and built a body for the landscaper I worked for on a peterbuilt SA that swung open one way and tipped open if left closed. I know Sanchez in Ledgewood builds bodies and is cheaper than transtar, but I do not know how his work is.
