This one seems to have an aircraft grade aluminum frame. Are there advantages to this ? Is it the only one ? Is it practical cost wise ?

That is a very nice looking frame. I like the way that they used an additional piece of aluminum to attach the axles to. I wonder why the cross members are only attached to the bottom of the main frame rails. The idea is to keep the frame rails from twisting which will reduce strength if they do. Maybe the trailer structure mounts to the top and keeps the frame rails from twisting.
I also notice that the axles don't appear to have much camber to them.
Maybe I missed it, but what brand trailer is it?

Yeah, I caught that same thing with the rail connections. It may be that additional cross braces are added once tanks and other under-floor connections are made. Or, as you said, the cabin structure ties the rails together.

I believe the trailer frame is an Oliver.
