How would you do it?

I think there are other designs that could work better, but the real problem is the amount of weight that you want to carry. You may have to fabricate something from scratch. This one has a better design and is 16" wide, but only a 60lb capacity.

Not sure i agree it’s a better design ... but it is a different design. The load is carried more vertically, which puts it closer to the bike but also raises the center of gravity. Either could work well, just have to evaluate the pros and cons and make a decision.

You’d take the cosine of the downward force vector by the square root of the tangential diagonal. Not really, just a bunch of random math and engineering terms. I’d probably just load it up and lift it by the tongue as a guess. I carry 40 pound bags of salt to my basement so that’s my baseline.

Thanks Guys
I have the weight end covered, have 800#'s + of bagged shotgun pellets,
all in 25#'s per bag. This will be my test to see the results. for 1 or 2 wheels.
The trailers are somewhere around Ohio??, from the tracking number........
coming from NY..........after 4 days of travel??

Guys
Here is some more information, per the user manual spec's,
the tongue weight should be between these rates, 6.6 to 17.6 lbs. (maximum trailer load/weight rated at 70#'s)
The trailer weights is 37.5#'s, it is approximately 65+" from hitch point of the rear bike wheel center to center of the trailers rear tire, the trailers load space is approximately 27.5" overall length and 18.5" in width, still looking for info.....

Tracking number still shows it's in Ohio?? Bad weather back there......?

To answer OP, I have a digital bathroom type scale and I can set tere. I use it to estimate bike weights and shipping bikes. First weighing one end then the other and adding them. I would put a sideways milk crate for the correct height on it and make that the new zero. Then I would put my tongue on it. And yes with some weights. The further the weight from the rear wheel and the closer to the bike the more the tongue weight.

The problem with a digital bathroom scale is that a person's pressure keeps changing because he's live weight. When the scale shows a steady weight, that's a digital guess.
I bought this a couple of years ago and never went back to my bathroom scale.

To use it outdoors on an uneven surface, I put down a piece of plywood. I sometimes weigh my loaded trash cart, weighing 47 pounds and rated for 200 pounds of trash. It's much bigger than the scale platform, but the readout can stay out of the way.

To find how much weight a cargo will put on a hitch, you weigh the cargo, then measure where its center of mass is, between the axle and the hitch. If it weighs 100 pounds and it's fastened 40% of the way from the axle to the hitch, it will put 40 pounds on the hitch.
