I bought this beauty from Clint, W3ARS in Shelby NC. He is a regular at most east coast and central states hamfests selling "Poles and Things" (HERE'S HIS WEBSITE), surplus military camo support poles as antenna supports. He has both aluminum and fiberglass poles. At the Shelby Hamfest last Labor Day, he had one of these trailers on display at his booth. This thing is a heavy duty frame supporting a 35' crank-up tilt-over tower. It was originally a military light tower, similar to the ones you see on highway repair projects going on overnight. It once had a big generator, a big electrical control box, and multiple kilowatt lamps (all now removed). But it did NOT originally come with the axle, wheels, or outrigger supports. It was built as a skid to be moved about by a big forklift. Clint says he got these things in as military surplus and that he and a friend worked up the additions and welded them together. They did a good job of it too. We arrived at a satisfactory deal and drove down to Shelby and picked it up a few weeks before Dayton. Now I'm building a HexBeam to go on top. This is my answer to a property deed restriction that precludes any PERMANENT structures to support amateur radio antennas. With a mast mounted on the tower, I'll have the base of my HexBeam up at about 45 feet I can't wait!
