I've done exactly what you suggest however I followed a process to insure it was safe. First, in order to mount the box on the rear of the Trailer, I took it to a machine shop where they fabricated and installed a receiver hitch welded to the trailers frame and it's good for 300# to 500#. Next I loaded my stuff in the rear box and went to the CAT scales for 3 weights (a-truck with trailer attached and WDH active, b-truck with trailer took off the WDH and c-truck alone). The difference between truck alone and truck with TT is imputed gross weight of the loaded trailer. The imputed gross trailer weight minus the CAT scales weight of the trailer is the tongue weight. First check is to make sure the imputed gross trailer weight is within the trailer mfg. stated weight capacity. Second check is to divide the tongue weight by the imputed gross trailer to see if the percentage is between 10% to 15%. If either check fails, make adjustments. If you are over the total weight, take stuff out of the trailer and put it in the truck (assuming you have surplus truck payload). If the second check fails, move stuff from the rear toward the front.
This is the way to do it. Weld to the frame, and add enough weight to lighten the hitch to the 10%-12% range (no less than 10% though).
