This was not from the oversteer concern, but do to the F350 rear suspension. When I returned the front to unhitched height, the heavy TW camper rocked the back of the truck to a noticeable point.

When I backed off a little WD, the 1 ton helper springs (overloads) just kissed the frame brackets and created a global shift in left to right stability.

The F350 way up high in it's suspension when the truck is empty is fairly soft, when you load it, it then becomes more stiff.

Same way with my Silverado 1500. My Silverado tows and drives much better with more compression on the rear springs than full restoration gave. I have Timbrens installed and they have little or no effect when all the weight is transferred back to the front axle, yet give a more solid feel when they are allowed to carry part of the rear axle load. This happens with about 50% restoration. I may be confusing some people, but I know what works for me.

Hi Tom,

In my case and maybe even in yours, my rear helper springs act like a rear sway bar on the rear axle to the frame to help stiffen the left to right stability. Now that we see you have Timbrens, they could be acting to help stiffen the left to right stability. And the only way you or I can get this to happen is by either more bed weight and or less WD. I have more bed weight, more tongue weight and a little less WD.

This may help explain to others that on your truck less WD allows more left to right stability due to the Timbrens coming in contact with the truck frame and stiffening up the back of the truck. That may help lessen the confusion.

Glad to here your rig works well.
