So the force applied by weight distribution caused this ( or turning too tight:

If it is bent, it is bent upward. I thought that might be caused by bottoming out in a dip. Could force applied by weight distribution bend it upward bouncing up and down the highway? I have only had effective weight distribution for a couple of weeks. The previous 2 years it was set up wrong with zero weight distribution/sway control. That's what listening to Equal-i-zer and following the instructions got me. 4 washers and weight bars parallel does nothing. If the hitch is bent upward, it could have been bent upward by my previous sob and EazLift?

I live in Mississippi. Surely I don't have to travel to Canada to get my hitch reinforced.

That bend looks like a jack-knife, or too sharp of a turn to the Right event to me. WD would not have done that, IMHO.

Don't believe you are understanding yet, we're not saying your hitch receiver is bent, we are saying your receiver cross tube may be flexing under WD load, and therefore negating the additional pressure you are putting on the bars by adding washers.

The fact is, you are towing a large trailer with a 1/2 ton truck, and probably right at max weight capacity and towing capacity.

I have weight distribution and sway control now, but the trailer is nose down. If I move the head up one notch, the trailer is nose up and I no longer have weight distribution or sway control.
My goal is to have weight distribution and sway control and have the trailer level. If it ain't possible, I'll live with having weight distribution and sway control and the trailer nose down.
I think by putting another washer in the hitch head or using washers to shim up the ball I may achieve what I am after.. If not, the trailer will be nose down and I will leave it alone.
You say may cross tube may be flexing under load. Flexing under load when? As I'm traveling down the road hitting bumps? I can't tell anything twisting or flexing when hitching up. I see no evidence of twisting or flexing when crawling around under the truck- no broken welds, nothing out of the ordinary- would the twisting and flexing flex the entire truck frame? I will have it looked at by Toyota and some shade tree welders. I won't drive to Canada to get it reinforced. I will get a local shade tree welder to do it. Then I will be exceeding my half ton payload in steel bracing...
Funny how I can turn tight enough to bend the hitch head but the trailer never gets into the tailgate and bumper. I guess that's why the Equal-i-zer shank is as long as it is.

Do you understand how a torsion bar spring works? Well, to a degree that's exactly what the hitch cross tube will do under enough load. Cross tube meaning the round tubular steel piece that goes from one side of the truck frame to the other.

In the beginning all weight distribution receiver hitches were built with TWO cross members, one in the back, and one about 2 to 3 feet to the front of that with the square receiver tube welded to both of them. It strengthened everything including the attachment to the vehicle's frame. This is what CanAM RV does to reinforce hitches so they distribute more weight.

It's normally not a problem when the tow vehicle and it's hitch is adequately rated.

Are you sure the head wasn't born that way? They aren't exactly precise stampings! I can't see you jack knifing enough to do that without other damage, as you state. WD didn't cause that, IMO.

I don't remember ever jack knifing, but with my rig I can turn the steering wheel all the way and turn in a circle as tight as it will go and the trailer will never get into the bumper or tailgate.
I have had to panic stop before- someone pulled out in front of me and I had to lock it down to keep from damaging my vehicle (or killing them- secondary in my opinion, lol).
Could sudden braking cause that? There is still the possibility that it was born that way. I just never noticed or never looked until someone suggested my hitch may be bent. I still don't really believe my hitch is bent or twisting under load, but I do plan to have it looked at by Toyota and a local shade tree welder (but he's a good welder).
The end result might be an aftermarket Class IV hitch and some other weight distribution hitch (even if I go back to an EazLift). The ultimate would be if I had $2,300 and could get a ProPride.

It would be jack knifing while backing...but again, other damage would've, been present. No, I don't believe hard braking would cause this....even if you had NO effective trailer brakes.

The only scenario I see is: born that way or backed into something with the head in the receiver (sans trailer), or being rear ended on head ( sans trailer). Both of those, you would obviously know about.

When you add a washer inspect the witness mark the big "rivet head" made in the shank. If it is oblonged to the side, something has caused the head "wings" to bend. If it looks round and shows no sideways movement, it was probably born offset. That is most likely, IMO.

My opinions are you did not bend the hitch head in a quick stop, and it's more likely it's always been that way.

It's also my opinion that another brand of hitch, even a ProPride will not solve the problem you are having with inadequate WD IF the receiver is flexing. Personally, I'd get it checked by your welder friend first.

right, the propride will just make the receiver flex, too.
IF that is the problem. Which it might not be. Its just something to consider, and investigate.
You don't have to drive to Ontario to have the hitch reinforced, but my understanding is that they are very generous with their advise; you could probably take that advise and have your local welder implement it.

listen to episode 196 of the Vap podcast.
Episode 196: Hitch 'em Up | The Vintage Airstream Podcast

Andy talks about this issue with the hitches flexing, and how things came to be that way (i.e. with the industry creating crappy hitches that often aren't as strong as they should be).

My Dodge/Cummins, Crew Cab 4X4 has base weights of approximately 4438 lb front, 2640 lb rear. As set up, loaded and with trailer hitched, my weights are 4400 lb front and 4300 lb rear. What does this mean IMO? I am of the belief that a weight ratio F/R of close to 50/50 is the best, or slightly front biased. So, I am as close as possible and the truck/trailer seems to handle well.

My suggestion might be to move the ball up one bolt hole if possible. Then, lower the weight distribution point on the trailer down. After this, see if the trailer is level, however this must be measured on a level surface, like at a truck weigh station. Also, look at the weights of the truck axles, and trailer.

Just my thinking today...

Already tried that-
It's funny how we went from sagging truck to droopy trailer-
The truck don't sag no more.
I still think a possible outcome will be the trailer stays nose down.
As long as I have good weight distribution and sway control.
As it is (trailer nose down) if I am going 65 and an 18 wheeler passes at 70 I feel nothing. If he is going 80, though, I feel the bow wave.

With enough wind and/or speed, you always will, even with a ProPride. At least, I did when I had my ProPride and every other hitch I have had. It isn't a problem mind you, but I feel it.

You could look for a ball with a 1/2" (or so) taller profile. (distance from bottom of flange to top of ball). But do not sacrifice weight capacity rating.
