The TR trailer is a typical aluminum trailer w/Torsion axles, disc brakes, and bunks that overhang the rear crossmember by 32". This really bugs me and while I have a plan to fix it, I don't know a lot about trailers and I'd like some input, or opinions......
In the first picture, the port bunk is sitting where it has been w/all the overhang:

The second picture shows the bunk turned around w/little overhang:

In the third picture, the two marks on the frame I-beam flange shows where I think the CG is now (the mark on the right), and where it would be w/the bunk overhang eliminated (the mark on the left) (aft is to the right).

Now, it seems to me that neither CG location is where it should be (of course my CG estimate is just a guess, so it could be off by 6"-8"). What I'm thinking of doing is moving the axles forward by relocating the rear bolt hole location to the forward hole in the frame and drilling a new forward bolt hole through the frame lower flange. W/the eliminated bunk overhang and the relocated axles, the CG should be better.

Now to the pointy end of the trailer.....the bow post would have to move forward the same amount as the eliminated overhang, so my current setup would have to change:

So I'm thinking by extending the 3" square tube that makes the tongue would be replaced by one about 30" longer so the post would be relocated forward of the of the frame, like this Magic Tilt trailer:

I'm looking for input as to whether this is a good idea, or not. Or am I wasting my time?
