Rear axle of truck should be slightly heavier than front by bout 150lbs if your WDH is setup properly.
if GCVW is not exceeded and WDH is adjusted properly everything else usually works out.
I have never heard of either of those. Most half ton and smaller vehicles end up exceeding some their rating well under GCWR. WDHs are properly adjusted when the front axle weight matches the unhitched weight and the TT is level to slightly nose down.
Its the same thing when you distribute the load the weight has to go somewhere in this case forward, I just said it differently. He can keep moving it forward as long as he doesn't exceed the max front axle weight ratio. Nothing wrong with a well balanced rig.
Rear axle of truck should be slightly heavier than front by about 150lbs if your WDH is setup properly.
This might be true for a particular TV/TT combination but, in general, is neither a desirable nor an achievable WDH adjustment goal.
For 41 sets of scales data reported by Open Roads Forum members, the rear axle loads with WD applied ranged from 460# less than the front to 1880# greater than the front. On average, the rear was 381# heavier than the front.
The proper way to adjust a WDH is to follow the specifications of the tow vehicle manufacturer. If these are not available, a good goal is to make the front axle load equal to, or slightly greater than, the unhitched load
Why is it not achievable or desirable whats wrong with a balanced rig? You said it yourself the average is 381lbs above in the rear, why not be above average. It takes time and patience to do it right and I realize not everyone has the mechanical skill to setup a WDH properly, but never say it cant be done. My final word to the OP is your tongue weight expectations may be a little unrealistic but proper loading can help mitigate this. The only way to know for sure is to go to the scales because you are so close to max GVW.
