vabuzzz,
This is how I am doing the same widening project you mention. My welders are slow to start.
The following is borrowed from Jim Marshalls post from long ago.

I finally got my carriage built to widen our Harbor Freight trailer to five foot. I didn't want to cut it down the middle and splice everything, as it would have been major problems with the tongue. Here is a picture or two of how I widened it to 5'.
I plan to cantilever the floor struts out 6 inches on each side and go from there.

Kayakrguy, I'm sorry I haven't gotten back to you sooner. I have the same problem sometimes with our PC not opening pictures.
My neighbor gave me some 2X2 angle iron so I made a frame 5 feet long and as wide as the HF spring carriage is. I cut the axle and bought a solid 1 1/4 inch steel rod which fit perfectly inside the U shaped axle tube. I also bought a 1 1/2 inch piece of angle iron and welded that from end to end to the axle tube that I had welded the 1 1/4 inch rod into. I located the carriage where the axle would be at 32 inches from the rear of the HF trailer frame and welded it there. When you build your floor, it will cantilever over the sides of your HF frame. Let me caution you at this point. I wish I had built the carriage for my axle less than 5 feet wide because when I put my aluminum on the side of my tear now, all that will cover the carriage that I built Will be the aluminum skin. Since I am using 1/8 inch plywood on my sides and adding the aluminum, I should have taken 1/8 inch off the width of the carriage that I built on both sides. This would have made my carriage 59 3/4 inch.
My friend, I sure hope I have not confused you. If I didn't explain this right please feel free to PM me or make another post here and I will try to make myself clearer. I am not very good at explaining things.
