I have a Flat Bed for a short box dually with hitch and mud flaps for sale. It't prepared to mount. I took the time to sand it down and repaint it and inspect the welds too add some support where I felt it was required. It's measurements are 8'-10" long and 7'-8" broad and tapers at the front. 34" inside measurement in between the main beams. Prefect for a welders rig!
If interested e-mail and we can establish a time to take a look at it,.
Thanks.
