I do hook up straight on, when possible. It doesn't seem to matter. It's the same either way.
I will take some more measurements of the bars and deflection when not hooked up. I've only measured it to the frame. The chains are the same on both sides, not twisted. I see no issue with the snap up brackets. I will try swapping the bars and see if it follows from one bar to another.
Trailer is heavier on the driver's side, which is the kitchen/bathroom/generator side, though the fridge and wash sink are on the passenger side. It's a toy hauler with no slides. I'm inferring that it's heavier on that side because that is the side that I almost always have to put boards under when levelling, no matter the camp site.
I'll definitely check the bars and make sure I don't have a bad one first. I still have the 1000 lb bars. I could see if they do the same thing. That would tell me it's in the hitch head. Since I have a new truck that is much higher than the last one, I had to get a new shank and drop the head down 5 inches, but the trailer is level now. Thanks for the suggestions.
