I have a problem and want to get some advise on how I plan to solve it. I have a 6-1 wide trailer. I was supposed to be 6-6 wide but the guy who made it goofed. It was delivered to me so late last year that I just accepted it as is and have lived with it ever since. But now I really need the extra width and dont have time to have a new trailer made. It is a tubing trailer with a 2 top rail about 14 off the bed. The top rail is mounted directly above the frame, and I am wanting to move it to the outside of the frame to gain the needed width (6 more inches). Here is what I had in mind . I am planning to cut off the top rail about seven feet from the rear. I then want to lengthen the 12 upright support tubes by 4. I am thinking of then welding on some pieces of channel to the outside of the frame and finally welding the upright supports (along with the top rail) on to them. If I make the pieces of channel stick out by say 1, I will gain an additional 2 in overall width, so that is my thinking. I then plan to also lengthen the top rail about 6 and tie it into the original part of the top rail section where it was cut, using gussets made from ¼ steel plate. I am hoping I wont compromise the strength and payload of my trailer by doing this. Any useful comments would be appreciated. Thanks.
