How would you do it?

Guys
If you were figuring out the tongue weight of a Single wheel cargo bike trailer, like this one,
How could you do it?

The only way I can see, is to make a stake to hold the tongue at the approximate height/location as when attached to the bike, set the stake on a scale's center, then add weights inside the trailer, in these 3 locations of front, middle and rear of the frame basket, to read the indicated tongue weight?
The trailer has a weight limit of 100#'s.

This tongue weight question has been asked, but no information can be found, so far.
Your thoughts or suggestions.............

Suspend the tongue with a fish scale. You can, of course just do the math.

Formula for Tongue Weight

T=W(Laxle - Lload)/Laxle

T : Tongue Weight (lbs)

W : Total Trailer Weight (lbs)

Laxle : Total distance from hitch ball to center of axle(s) (ft)

Lload : Distance from hitch ball to the center of the load (ft)

Fish scale works, if you buy one with a high enough rating. I’m thinking most inexpensive scales are under 20-ish pounds. And how many times are you going to use it? Your idea of a bathroom scale is good, it has the capacity, but i don’t understand why you need to do it 3 times. Load it up like you normally wolud, and weigh it. The wheel in your picture is at the far back … in a full size cargo trailer the wheels are in the center so its possible to put load behind the axle to reduce tongue weight.

Guys/OTG
Since I know nothing about using this type of trailer, I plan on doing a scale check using the OEM 1 rear wheel, check everything, then add the second rear wheel, test the same way, and see the difference, between the two.

I have a feeling that the direct location of the load, will have an effect on the towing and bike handling results.

As this will be my Big game meat/load hauling trailer, I NEED to know the end results, so I don't get cross threaded on the Mtn with a load of meat on it.
If possible, I would like to be able to haul out around 200#'s in a load, to reduce the number of trips back to camp.

Plus, I have the better half's 120+# Shepard that wants to follow the bike,
and I know he can't stand up to a 10+ run.

Here is an example with some assumptions, since I don't know the dimensions of the trailer:

W : Total Trailer Weight (lbs): 225 lbs
Laxle : Total distance from hitch ball to center of axle(s) (ft): 5 ft
Lload : Distance from hitch ball to the center of the load (ft): 2.5 ft
T=W(Laxle - Lload)/Laxle: 225 lbs (5 ft - 2.5 ft) / 5 ft
T= 112.5 lbs
