earthspun:
I think it might be very difficult to achieve 1/3 on each
axle or
axle set.
Example my 2005 suburban 2500 cat ticket full fuel and wife and I included is 3780 front
axle, 3140 on drive axle
With trailer (2008
Bigfoot 25FB with cargo box) attached with out weight distribution hooked up 3380 front, 4300 rear, 6000 trailer axles
with (Andersen)weight distribution on 3480 front,4160 rear and 6020 trailer axles.
I transferred 100# back to the front axle and removed 140# from rear axle and transferred 20# to the trailer axles.
These weights are not fully loaded, fresh water was empty for this weighing( 45 gallon capacity mostly centered over the axles)
This may not be ideal but I didnt wish to make more adjustments and re scale measurements, I did tighten the chains another turn of the adjusting nut after fully loaded but did not re weigh, and it has towed level and well for over 8k miles this past
fall.
Most trucks that I am aware of are rated to carry more load on the rear axle than the front which is figured in to your payload capacity.
My understanding is to keep front weight near original not too
light you don't want to lose steering ability especially in poor road conditions.
