OP, it would help if we knew what truck. Looking at your posts all I could find is it's a diesel. Glad you are finally getting on the road.
IMHO you cannot have too much tongue weight, especially with a diesel PU. Only time I've ever had a problem was when I loaded some very heavy bargains in the back of my Airstream TT as it tried to take me to the scene of the accident. Applying the trailer brakes while accelerating got it under control and then slowed down and moved half of the stuff to the front.
Sounds like you have actually weighed your rig so what's your axle weights? I pull a bunch of different types of trailers without using WD as I can vary the tongue weight by where is place the load on the trailer with my F350 diesel. Doubt your rear axle is near it's max so taking some off the front with your 1000 bars does not bother me.
