I don’t like the vw jack either and got a bottle jack which would lift the van high enough to change a wheel which works well for routine maintenance but realised that with a flat tyre it wouldn’t fit under the jacking point. Solution was to use a smaller 2 ton bottle jack on a suitable point which would lift the van body enough to get the bigger jack in place. Seemed like a bit of overkill carrying 2 jacks but actually the 2 bottle jacks take up less space than the vw original and a lot safer.
