The 5 dump manifold shown above allows you to lift or lower the front and back idividually. You can also lift straight into a side from layed out with the manifold. Also, dump each corner individually...hell, you can even lift straight into a 3 wheel if you want!!!
Please feel free to ask questions on this thread, but lets limit myself to answering those questions, as obviously our products differ from the others out there.
