WD proper setup-bars-and level tow vehicle

I am using a vintage Suburban 4x4 towing a 19f Mallard around seeing the kids and sights. My Suburban is a k1500. 16" tires. The hitch is a 10k hitch installed after-the-fact when we bought it last century. I think tow capacity is 6000 on this unit. Not sure. The Vortex is built, the trans is built as is the transfer case. No powerhouse but runs 10mpg all day long at 60.

I swapped over to a Harbor Freight WD bars and connectors on the trailer tongue. But still using the old EZ Lift receiver.

Previous bars were much lighter than the HF ones, (I got a killer deal so I bought them). These bars and chains are much heavier than the previous setup, plus those bars were over 20 years old if not more.

RV guy in another high end unit approached me the other day. He said when I came in the parking lot he saw that I had my bars on the trailer way too tight. He said his experience told him to tell me to lower the links down by at least one maybe two. He said I am risking a chance of riping the chains off the trailer mounts by having the bars so tight.

I thanked him, went on. OK...previous setup the Suburban would sit a bit down in the back when connected. But the trailer was level.

The new HB setup, I have the links at #4. The Suburban is level, the trailer is slightly up end, higher in the front than back on level ground. Just a bit, but not level and not noticeable unless you look at it carefully.

I did not notice any difference between either setup.

When I was putting the new bars on, I did make the setup tighter than before.

So, what is the standard rule of thumb?

The Suburban is heavy. Probably in excess of 6500 then add all my stuff, two dogs and a computer I bet it is beyond that.

The trailer is said to be about 4k empty. I am far from empty. I am loaded heavy. Food, water, stuff I bring along, including a spare generator, I am sure I am tipping over 5k. When I get a chance I am going to weigh the whole setup just for curiosity's sake.

13k maybe a bit more.

So what is the rule for setting up the WD bars. I also have a slide brake which really does keep the sway down when a big rig comes flying up behind and passes you.
