We just got a 8K 22.5 foot bumper pull after towing 5th wheels for years. Hitch is Pro Series with sway controller. Dropping two links I still have 300 pounds removed from the RAM 3500 4x4 Diesel trucks 5200 lb front axle. Hitch is has the extended drop insert for the high truck, which also sticks back quite a ways. The tail gate if the truck is straight with the trailer just clears the tongue jack when down. To drop a third link I would have to really raise the back of the truck and tongue with the jack, so I am staying at the two link drop.
Remember also as the equalizer bars transfer weight from the truck rear axle to the trucks front axle, some of the weight also goes to the trailers axles.
