I'm thinking I need a very powerful impact wrench to get this thing started (and get 400 ft. lbs of torque) Any suggestions or am I on the right track? Also any suggestions on who would have an impact wrench that powerful? I stopped by a couple automotive shops but they didn't have anything near that?
Thanks,

Haven't yet, picking it up on Saturday. I'll let you know. I went with a Blue Ox 1500 tongue weight, 15000 weight carrying, its about 1000 more than I needed, but I like it that way. I can tell you from putting it together it is seriously heavy duty, the shank+trunnion+spring arms weigh a total of 110lbs! 
, and once again I like it that way. The blue ox also has sway control adjustment built in to the spring arms. I will post a full report on the results when I return.

Here's what I ended up doing. Put a towel over the ball so as not to scratch it, clamp with vise grips, turned nut to v. grips hit the shank so it was holding itself in place, cranked on it til i couldn't get it any tighter, then put a 4 foot long breaker bar over my 3/4 socket wrench, cranked on it til i couldn't move it even with the breaker bar, then a friend helped me and we turned it another full revolution.

The weld isn't a bad idea. I'd rather throw hitches away every month than have another come off.
I also use a grade 8 bolt instead of a receiver pin and have replaced all the hitch mount hardware with G8's. Never use a thread lube, amti-seize or locking compound on a G8 bolt. Lockwashers and torque wrenches. Welds are good too.

Put some lubricant/grease on the ball--this will make sure that the trailer and ball hitch don't rub too much to loosen the nut.
