The idea of building a trailer out of a banjo housing is nothing new. 40 years ago any axle with good wheel ends was used for something. However, the hydraulic lift is something new to me. All of my bulk trailers and my flatbeds have air lift axles because they run empty a lot. I had never thought of using hydraulics. Empty trailers pull so much easier with one axle up. You never get too old to see new ideas.
