Your tongue weight will be the most when the trailer is empty of toys. When you put the toys in the rear, it reduces the tongue weight.
I would purchase a WD hitch that is rated for the heaviest weight the tongue will see which would be unloaded. You do not want one rated for under that weight because you will probably not tow it all the time with the toys in the rear.
I think I would purchase a WD hitch with a max rating of 2000lbs tongue weight. Your trailer A frame should be rated for at least that amount since toy haulers have heavy tongue weights. Also make sure the ball you use is rated for the amount of weight you will be towing.
When setting up your hitch, I would put the ball about 1inch above the trailer coupler. If that amount results in a trailer nose high condition then lower it to the next hole down on the shank. Make sure your shank allows you some movement up or down when you decide on a length of rise or fall. It is better to have it too long rather than not long enough.
Remember, you level the trailer via the position of the hitch on the shank - not by adjusting the WD bars.
If you decide to purchase a
tongue weight scale, I would get one rated up to 2000lbs.
Hope this helps a bit. :)
