Yes. If you add 1000lbs to the trailer your tongue weight will go up or down depending on where the weight is added. In front of the trailer axle(s) and tongue weight will go up. Over the axle(s) tongue weight will probably stay the same. Behind the axle(s) and tongue weight will go down.

If you read some of the many threads in this section, you'd see the explanations time and time again.

In short, the average trailer puts 13% of the weight on the tongue. So, 100 pounds of trailer leads to 13 pounds on the tongue. Your 6,100 pound trailer, ON AVERAGE, puts 793 pounds of weight on the truck, dropping your payload to 867. Subtract 100 pounds for a weight distribution hitch and you have 767 available pounds for you, your passengers, their stuff, and any other mods you made to the truck.

Working the math:

Your 1,660 pounds of payload, minus the weight of you and your passengers, minus 100 pounds of weight distribution hitch, equals the remaining payload.

Assuming 500 pounds of passengers, plus 100 that's 600 pounds to subtract from 1,660, leaving 1,060 of remaining payload. But your hitch is constrained at 1,050...

Working more math:

1,050 pounds max tongue weight with WDH, minus the 100 pounds for the WDH, = 950 max tongue weight, which also leads you to a max LOADED trailer of 7,308.

You need to drive to the scales, weight the truck full of gas with the normal stuff in it (not you), weigh the loaded trailer, weigh the tongue, weight the trailer loaded on the truck with the bars tightened...

Rich gave you the answer. I'll clarify a tiny bit.

You need to know the actual payload capacity available for hitch weight. Payload capacity available for hitch weight = GVWR of the tow vehicle, minus the wet and loaded weight of the tow vehicle. The only way to get close to that number is to

1] load the tow vehicle with everybody and everything that will be in it when towing. Don't cheat yourself. Put it all in. Campfire wood, tools and jacks, toys, generator?, fuel for the toys and generator, everything that weighs more than a handkerchief that you might haul when towing.
2] Drive to a truck stop that has a truck scale. A "truck scale" has at least 3 pads, one for the steer axle, one for the drive axle, and the third for the trailer axle(s). Most common is the CAT brand truck scale.
3] Fill up with gas
4] Weigh the wet and loaded tow vehicle without a trailer
5] Subtract the weight of the wet and loaded tow vehicle from the GVWR and the answer is the payload capacity available for hitch weight.

"Enough tongue weight" = 12% to 14% of gross trailer weight, averaging 13% of gross trailer weight. Most experts state you need 10% to 15% tongue weight, but I've found that at least 12% is better for minimizing the tendency for a trailer to want to sway, and more than 14% doesn't help anything but requires more payload capacity available for hitch weight. So aim for the 13% average, but settle for anything between 12% and 14%.

So you need to know not only tongue weight but gross trailer weight. The best way to determine those numbers is to weigh the tongue of the trailer with a tongue weight scale, then weigh the tow vehicle and trailer on a truck scale, without the spring bars of a WD hitch, to get trailer axle weight.Tongue weight plus trailer axle weight = gross trailer weight. Tongue weight divided by gross trailer weight = percent of tongue weight. Attempting to determine those weights without actually using weight scales is an exercise in futility.

If you don't have access to a tongue weight scale, then you can determine actual tongue with two passes over the truck scale. The first pass is tow vehicle and trailer hitched together, without the spring bars of a WD hitch. The second pass is with the tow vehicle only, without the trailer. Add the weights on the front and rear axles of the tow vehicle to get GVW. Subtract GVW without the trailer from GVW with the trailer and the answer is actual tongue weight.

Hitch weight is tongue weight without a WD hitch, plus the shipping weight of your WD hitch. So "enough hitch weight" means you have enough tongue weight. If you have enough tongue weight, then you'll have enough hitch weight.
