Why are the sign posts and T pole so tilted.

You got an answer that said no. That answer is technically correct. It does not reduce the tongue weight. However, your example of how it would reduce the impact of that weight is key (ie distributing some of the weight). The weight is still there, but when distributed, it is carried by the front axle of the tow vehicle and the trailer tires. Note as well that the hitch has mass and therefore, adds weight to the tongue.

It's like sitting on the ground and then lifting your bottom off the ground in an upside down pushup. The weight is still there, but the ground is no longer supporting it. Your hands and feet are supporting the weight.

There are three issues to tongue weight. 1) The impact of that mass on the directional stability of the rig. Assume 10-12% of the total mass of the trailer should be tongue weight. 2) The impact of that mass on the tow vehicle hitch receiver. The receiver must not flex and must be strong enough to transfer the required weight. 3) The weight transferred must not reduce rear wheel traction or braking power. It is an exercise to balance the weight for best performance. Don't raise your bottom too much.

Thanks to Andy for the above post. Nothing makes a point quite as well as a picture. That tilting pole must mean there was wind involved in the climb or the ground is shifting from all the power being applied.

Travel safe and with a smile. Pat

“Weight”

There may be some misunderstanding over the word “weight.” A weight distribution (WD) hitch distributes the static downward forces which result from the mass of the trailer and gravity. The WD hitch does not redistribute the masses involved, only the static forces (when the spring bars are loaded). Of course the WD hitch does increase mass at the hitch, and this would increase the tongue “weight” (downward static force) at the hitch receiver - until the spring bars are loaded. The pitch bending moment from the loaded spring bars will redistribute the static forces, such that the static downward force at the hitch receiver on the tow vehicle is decreased. This was the expressed concern by RobynE.

I hope my remarks are clarifying, and not adding more confusion! RobynE should be reassured by Andy Thompsons posts above.
