Group 24 Battery 38LB and Boondock Tire 57LB.
We started with the trailer loaded as we normally travel:
*No Yakima Racks on the back, as they are on our truck to carry kayaks (they don't ride well with the rack installed on the trailer )
*Also missing are food provisions, clothes, pillows, etc. from actual travel setup.
*Pots, pans, first aid kit, bottle jack etc. are always in the trailer and were included in the data collected. Full propane tank too.
Initial Thoughts:
Crunching the numbers you'll find what I guess are rounding errors on the scale's part (a pound here or there).
There is quite a bit of info to ponder here. I asked one of our sons, a mechanical engineer, how to calculate the effect of a heavier battery on the tongue weight. He just made my brain hurt with beam loading Theta this and that. His brother offered to bring over weights to place in the tub so I could measure (not playing favorites, but I know what I'll do to find the weight of a potential new battery set-up )
Here are a few photos from the weighing:
Ready to do a tare weight on the scales and zero them out.

You mentioned the weight of the full fresh tank only increasing the tongue weight by 5LB in my data. There are three points where weight is distributed downwards from the trailer, the wheels and the tongue. The proximity of the weight to one of these points determines what percentage of the weight it carries. The chart shows that the fresh tank water is primarily distributed to the wheels (mostly on the passenger side) because the tank is closer to them than the tongue.
The data also shows about 63% of the weight added in the area of the tub was distributed to the tongue (because the tub is closer to the tongue than wheels). This is based on the weight difference shown with or without the 38LB group 24 battery.
Two 77LB, 6V GC2 batteries (154LB total) in the tub should increase the tongue weight around 97LB over an ‘empty’ tub (no battery, full propane tank). I would expect in my case the full fresh tank, GC2 batteries plus tire on the platform to bring my tongue weight to about 300LB.
For anyone trying to do all the other calculations, that would be 12.8% of the new total trailer weight. This is well within range of excepted standards.
I can't speak to the example @Verna mentioned earlier of the broken tongue. As I understand it, as long as your TV can safely handle the tongue weight, your specific mod should be no issue. As @Denny16 and @db_cooper mentioned, it should even reduce potential trailer sway.

Just tightened the battery terminals with leads added to a noco genius 10. Project now truly done.
Planning a shortish trial winter trip in 3 weeks and can't wait...
