Nice work on the bumper but I am a little concerned about the fabricators choice of "latching" the swing-outs. Hopefully they aren't finished and thinking of some compression latches to securely fasten those arms to the bumper - I see that area has been cleaned of paint and is raw steel - hopefully that set-up is temporary.
The way you have your truck built and the likely intent of your travels, those pins are going to put you in the hurt-locker real quick. Compression latches would be an easy addition and would draw the swing-out arms in tightly to the bumper making for a very solid connection.
