AsterixThis is off topic - for which I apologise - but is your car fitted with Continental Premium Contact tyres - the tread pattern looks similar. If so - how do you find them for cabin noise?
I've never seen measuring like that done before Asterix although I can see what you're trying to do.
But there could be marginal differences in the panels or their mounting from one side to the other.
Was one of your winter tyres worn more than the other?

The measurement is taken from the Spirit level to the tyre sidewall, so who cares about the panels. As far as the adjustable rods are concerned, yes they are expensive but so are 2 rear tyres that have worn unevenly and have to be tossed away. I believe your concern is when towing & 4 adults in the car, so if you got the adjustable rods, how would they be adjusted for this type of weight situation and what would happen when you're not towing or driving with less people, to me it's always going to involve some form of compromise.
How much weight does your van place on the rear suspension Asterix & do you have those caravan levelling spring things fitted to your caravan A frame
do you have those caravan levelling spring things fitted to your caravan A frame

None of the km's on the wintertyres are with the caravan.

The measurement is taken from the Spirit level to the tyre sidewall, so who cares about the panels. Yeah. Sorry. I should have put my glasses on to look more closely at the pics. However, Asterix makes the point that there is a diference from one side to the other but the rear camber settings are the same on both sides. Assuming the alignment settings are correct I can only assume there is some small difference in the way the spirit level is being read. It's not possible to be sure the ground is level, the car is level and the spirit level is totally accurate on both sides. To explain those a bit, a minor dip in the road surface would be enough to put the comparison between two side out. The car on an alignment machine sits (or should) on turntables on rollers which ensure the suspension is settled evenly on both sides. The bubble in the spirit level, especially in a vertical position is only positioned by eye. And if that was accurate enough there would be no need for a wheel alignment machine.The car is sitting on what appear to me to be pavers not a level slab of concrete (but I might be wrong). And looking at the wall in front of the car (again, it's hard to tell) but it appears to be on a light slope where the floor butts up to it.

None of the km's on the wintertyres are with the caravan.The levelling springs help. But 60kg at the drawbar is only what it is at rest. So Acceleration, braking and dips in the road all magnify this figure or reduce it.

None of the km's on the wintertyres are with the caravan.Although the handbooks generally say set alignments with the car empty, I know from personal experience that this is not necessarily going to give the best result. I would be inclined to pay a bit extra and take readings with two people in the car and again with four, just to see how much if any, difference it makes. If there is no difference then that's good. If there is some, a good alignment operator will have some idea what allowance to make to optimise the wear (it probably can't be eliminated).
This is a good point. Even if you have the adjustment option, it's not necessarily going to fix the problem, although it might move the wear issue to the outside shoulders, depending on when you are travelling loaded or not.
I hope you investigate the ride leveler springs, they allow weight to be transferred to the driving wheels of the car. Do you have any problems with night vision and the lights pointing up to the treetops instead of on the road. The springs are extremely popular here, my friend had them fitted and says they make a huge difference to the handling of the car / van too.The most respected brand here in Oz for towbars is Hayman Reese. Use the advantage of the internet and have a chat with them.
