Uneven tension between left and right
The force required to lock in the right bar is CONSIDERABLY more than is required for the left bar.
This is a Husky 1200# round bar setup. 5 links under tension both sides. ALL measurements are equal between the two sides. Laying the two bars on top of each other show no difference. When hitched up the distance from the bar to the frame is the same on both sides. Swapping the bars for left/right makes no difference. The right side is always MUCH stiffer than the left.
Actual towing seems to be fine. Front fender measurement is the same hitched/unhitched. Rear measurement is 1 1/2 inch lower when hitched.
Is it normal to have unequal tension for each side? If not, what can the problem be?

Is the camper level? Are you always doing the right side then the left, or it doesn't matter which side gets snapped up first?

Trailer is level. Doesn't matter which is first. Right is always a LOT harder than the left.

I have the same issue
I also have the husky 1200 bar for my 26BH. The right one can only get tow links on while the left one can go up to the third link. This happens if it is level or not.

Is it acceptable to have a different number of links on each side under tension as long as neither is less than 5? This would tend to equalize the force.

Hmmm, I no longer have my Husky 1200# round bars installed but I never noticed this when I did have that hitch on the 22FB. Could it have something to do with the hitch head?

I see no visual reason for this. The hitch head is perfectly symmetrical.

I'm wondering, with everything hooked up, except the chains disconnected and hanging free, is there a difference in the distance from the bar free ends to the TT frame? If there is, this may indicate the pivots in the hitch head may be different, not lined up with each other.

Nope. Distance is the same.

Okay....when spring bars are made, the final step is to "temper" the metal by first heating them very hot, then "quenching" them with cold water. There can be variability in this process, and it could be you have two different batches there. Could be their process control is not consistent from batch to batch.

If that were the case would not swapping sides with the bars also swap side with the problem? As it is the stiffer side is ALWAYS the right side even if the bars are swapped.
Thanks for your input though. This is a toughie.

Seems like that would the case. I wonder if the hitch receiver is perfectly level?

Yes, it's level.

Not unusual to have the first spring bar being engaged (round or trunnion bar) to require a little more lifting force than the remaining spring bar.., and it's more noticeable if the TT tongue jack isn't extended enough to relieve some of the load.
I would not recommended to have different chain links "under tension" to address the dissimilar lifting force required to initially engaged a spring bar.., because it's my understanding that once the tongue jack is fully retracted the pair of WDH spring bars tend to equalize their share of the load for proper weight distribution and support of the loaded tongue weight...., especially while the TV/TT is in motion.
As far as the same side of the TT A-frame always reflecting the higher spring bar lifting force, it could be attributed to a number of things (I'm thinking out loud here);
* The relationship of the spring bar to the side of the TT A-frame.
* The relationship of the draw bar within the receiver pin box.
* Design of the ball mount.
* Elongated hitch pin hole in the receiver pin box do to the use of standard hitch pin (inside radius wears pin box clearance hole).
* Ball mount wear at spring bar contact points.
* No two spring bars are totally identical (?).
Also, it's good practice to use the same spring bar in the same side of the WDH ball mount to minimize the wear of the corresponding metal parts.

Thanks, Bob. I have pretty much resolved it is just the characteristic of my set up. Nothing can be/has been determined to be wrong. It is a new trailer and a new hitch. Has been towed 4 times. Less than 100 miles total.

Chuck,
Without actually seeing your WDH set-up, I would tend to agree. To confirm that your WDH is correctly adjusted and distributing weight properly, a brief visit to a CAT scale will tell you everything you need to know plus provide a little piece of mind.
