So from that ID tag, the GVWR of the truck is 6010 lbs.
It doesn't list the curb weight, but let's say it's 5000lbs for example.
That means you have 1010 lbs of capacity.
Tongue weight of the trailer + gear in the truck + passenger weight should not exceed the 1010 capacity.
The towing capacity of the same truck may be in the 7000lb range. That means that the GVWR of the trailer should not exceed 7000lbs
Many folks also think that you should have room to spare for both of these numbers
