I seek wisdom - I am in short supply.

I realize that 'house trailers' come in a variety of qualities - from trailer trash to fine homes on wheels. (When I say 'trailer trash' I am speaking of the structure, not its inhabitants.) My question is the axles that they roll in on.

I have access to 100 or more axles - some 8 feet long and some 12 feet long. They all seem to be 3" sch 40 size pipe. Most of them do have a bit of a wow or camber in them, I assume to flex as the trailer travels.

Here's my question. I want to add gin poles to my truck. If I cut off the spindles the pipes would be the correct length. I realize that a length of 3" pipe, new, would only be about $100 but free is hard to pass up. What quality is the steel in the axles? Is there any reason that the 'axle gin poles' would not work. My winch is only 8500 pounds so that would be my limiting factor.

I could not find a single tag on any of the axles - so I can't call the manufacturer.

Thanks!
