Other than the 2" receiver stub like yours, mine is made from used oilfield pipe. 2-3/8" pipe spanning gooseneck uprights,resting in 2-7/8" cradles on each end. Receiver welded to a piece of 2-7/8" which is slid over 2-3/8 above. The only weld that must be top quality is receiver to 2-7/8" pipe which can easily be done by a qualified welder in their shop.
A simple stand with roller placed on rear is needed to hold cable off deck until load comes onto deck. A couple 20k snatch blocks are indispensable for off-center and other unusual situations. 4x4,6x6 and 2x6 cribbing comes in handy. In addition to lockable toolbox I have an expanded metal basket on tongue for storing accessories and chains.
A couple running lights on front corners are wired to #7 of 7 way plug plus #4 with switch and diode so lights can operate from trailer battery whether hooked to truck or not.
My winch cost $1,400 so I have anti-theft provisions it would be difficult to explain for you.
