took a quick read of you guys thread on the "egg forum"...
Is this trailer too much for a Touareg - Club Touareg Forums
nickM and aircooled (westfalia here) are both giving good council regarding the OVER load issues...
you both appear WAAAAAY off track in understanding what w/d does or does NOT do...
IF
thinking that w/d somehow allows for MORE than the stated/rated tongue weights.
w/d does NOT take weight OFF the tongue/A frame...
whatever the tongue weighs is WHAT IT WEIGHs...
what w/d does do is REDISTRIBUTE the SINGLE POINT load (if the tongue were on a post)...
such that MAGNIFIED load at the drive axle is reduced and the SUBTRACTED load at the steering axle is restored.
but it does that by INCREASING greatly the stress/forces at the receiver/hitch/A frame...
it does NOT LIFT the A frame in the simplistic way it appears u think...
the reason vw specs tongue load the SAME with/without w/d is another issue...
and relates to HOW the receiver is attached to the unibody and WHAT w/d does to that attachment.
____________
geo'/simon, the A frame weighs whatever it weighs...
NONE of the hitches (including the PP) 'take weight OFF' the A frame in such a way that one can GO OVER the ratings...
that's magic math and doesn't happen.
read the LATER posts in this thread on the w/d experiment...
starting at ~post # 30 (read the early posts too)...
http://www.airforums.com/forums/f464...rol-17986.html
there is NO LIFTING at the ball that REDUCES the actual weight AT THAT AREA...
in fact there is PUSHING DOWN at the ball area and HIGHER torque/force, over the simple DEAD weight of the tongue.
____________
there are 100s of threads here where...
1. folks know the tongue weight (or estimate)...
2. that tongue weight is OVER some limit (hitch/payload/axle/receiver)
3. and they ASK the question...
"will using a w/d LOWER the tongue weight so i can be within limits or so that i can ADD more weight to the tongue...?"
the answer is always NO.
there is no magic LOWERING of the tongue/A frame weight by using w/d gear...
the tongue weighs what it weighs...
w/d alters HOW that weight is carried by the tow vehicle (receiver/axle/tires)...
but doesn't ALTER the actual tongue weight...
and actually increases the stresses/loads at the receiver.

"egg" or air...
the thinking IS flawed regarding what w/d does and ratings/capacity changes.
