Help with scale numbers

Weighed at local grain elevator and here are the numbers

truck by itself
steer axle-3240lbs
drive axle-3000
gross weight-6240

tt + tv- WDH(equalizer) bars disconnected

steer axle- 2940
drive axle- 4200
trailer axle - 5360lbs.
gross weight- 12500

tt + tv-WDH engaged

steer axle- 3060
drive axle- 3900
trailer axle- 5540
gross weight- 12500

tv is Rockwood Ultra Lite, ship weight- 5676, hitch weight- 739
gvwr- 6739, this info taken from web site, yellow sticker on side of tv for dry weight is 5840lbs

tv iv 2012 f150 EB, screw, heavy duty, payload is 2440lbs.

please ?check my math

total gross weight mlnus truck gross, engaged = trailer weight = 5540lbs

tv engaged Wdh minus tv unhitched = 720lbs , weight transfered to tv

tt hitched axle weight minus tt unhitched axle weight = 180lbs.

720lbs. + 180lbs. = 9oolb tongue weight

tongue weight is 16% of tt weight

front axle tv unhitched minus hitched front axle = 300lbs.

engaging wdh put back 180lbs to steer axle

is tongue weight added to tt axle weight to get tt weight?

any adjustments needed?






any adjustments i should make to wdh?
