Pack a tow rope and a couple of rated bow shackles. You'll make it home then regardless ;)
I'd be less worried about electrics than I would about both of the issues Philip mentioned.
test the coolant for combustion gases before you leave, check the fluids in the transmission and transfer case, swivels & diffs, And the usual roadworthy items.
Since you're a mechanic, noone has to tell you what to bring. You already know the triton will have all your gear in the back :D
Send some pics when you get there, and post a few of your road trip. Best of luck and hope you get it home without any issues.
