Here is my TT:

My truck:

2020 Toyota Tundra SR5 CrewMax w/5.7 V8 5.5ft bed

https://www.toyota.com/tundra/features/weights_capacities/8261/8272/8275

CAT scale weight - 5860lbs total or 3320lb steer and 2540lb drive

Tire loading sticker - max occupant + cargo 1270lb

GVWR - 7200lb

Hitch:

Equalizer anti sway and weight distribution hitch

I looked at specs on that trailer. 555 lbs is "dry" hitch weight. 4685 is unloaded trailer weight. 6500 is GVWR of the trailer.

Here are some things you're missing:

Average load of dishes, pots and pans, bedding, camp chairs, BBQ equipment, groceries , water, etc is 800 to 1000 lbs. That would make the trailer's loaded weight about 5685 lbs. More, if you're carrying bikes and toys. You should plan for trailers GVWR of 6500.

Average tongue weight is 12 to 13 percent of loaded trailer weight, and it is not a constant number. Tongue weight fluctuates during every trip.

A weight distributing hitch weight 80 to 110 lbs.

The weight of your weight distributing hitch and loaded tongue weight are counted as cargo weight in the truck.

Thirteen percent of 6500 (trailer's GVWR) is 845 lbs. Plus a WDH, would mean the trailer needs to use at lest 945 lbs of your payload.

1270 payload minus 945 tongue / hitch weight = 325 lbs available to carry passengers, luggage, car seats, cargo, etc.

The closer you get to going over max weight, the more unstable / unpleasant your towing will be.
