I also wonder if those 2x12s are treated? They look untreated in the pic.

Good deal though!

I am looking at having my uncle build me an aluminum 36ft goose neck lowboy. He builds aluminum car haulers all the time, but he hasn't done one that big. Just have to figure out the materials cost. A new one costs somewhere in the 20K range, he is trying somewhere in the 5K range. That would be sweet!!!!
The frame is 4" channel iron (I think that's what you call it) except at the far rear cross bar and was sturdy enough to haul a large skid steer with attachments for a long time. I'm going to be bracing the frame at the rear more, since it will see a larger area of weight than the skid steer laid down. The wood is "kiln dried, heat treated lumber", and after I get everything cut and drilled where I need it I plan on treating it with a weather sealer. Here is what I got done today:

Laid the wood out just to get an idea of how it will fit:


Cut the rear section off:




Cut alot of excess metal off that was sticking up:


Welded in a piece at the far rear for the ramps to attach to. Going to be using a larger brace just forward of this area to run the width of the trailer:
