as weight is taken off of a wheel the chassis pushes the wheel downwards to always have contact with the ground. it is very visible and quite alarming to the casual observer. as you move the van on its axis the weights transfer accross the axles and this effect can be seen.
you have just run into the downside.
I have been discussing this with a fitter of powertouch movers and he said he always has to take the twin axle quad movers for a test run spinning them round to adjust them 100%. In theory the closer to the middle of the tyre the mover is the less the effect should have.

We are changing our Louisiana for a Schooner and intend to have our Reich 4WD mover moved to the new van.
Mentioned the Reich changeover to the Dealer when we ordered the Schooner and he said that he had put them on other Buccaneers without any problem.
I will ask if he is aware of this situation.

Welcome to the forum.. It would appear that you have tagged you question onto another subject, it would be better
as a new thread.
Thanks Ken, new thread started - GPS

The swing VTEC chassis flexxes to keep maximum tyre tread on the road. and is proven to provide safer road handling etc.as weight is taken off of a wheel the chassis pushes the wheel downwards to always have contact with the ground. it is very visible and quite alarming to the casual observer. as you move the van on its axis the weights transfer accross the axles and this effect can be seen.
With a conventional straight caravan axle the stub axles remain parallel to the axle as the suspension rises and falls. With the V Tech (and Alko's version) the axle tube is bent so the stub axles are not parallel with the axle, and therefore the wheels change angle in relation to the road surface as the stub axle goes up and down. This improves road holding by keeping more tread in contact with the road surface. It would interesting to know if it affects tyre wear as it would seem that the tyre is constantly changing direction on the road surface

When turning manoeuvres the outer wheel will tow-in at a negative camber, whilst the inner wheel will tow-out with a positive
camber. This gives improved cornering ability by allowing increased tyre tread contact on all wheels and minimising body roll.
V-Tech design also has the effect of moving the touring caravan roll centre axis closer to its centre of gravity which further improves
stability by reducing body roll.
