Which jack is best?

Any of the jack types listed will work PROVIDED the van is still attached to the towing vehicle and it is on firm ground. Remember that an uncoupled van will rotate on the jockey wheel when one side is lifted and will fall off the jack.

Most bottle jacks will have leaky seals over time. A lesser probability for trolley jacks.

Scissor jacks will 'rotate' vertically as the van is lifted (as do cars) whereas a bottle jack won't. A trolley jack will move inwards if it is on a smooth hard surface.

You will get lots of replies all giving a user's preference.

Do not use a trolley jack on the Al-ko jacking brackets.
I did some years ago and they collapsed. The trolley jack tries to pull the caravan .This puts a lateral load on the brackets which then bend and disaster.

I now use a bottle jack with no problem.
The two I had from purple were rubbish but their brackets are excellent.

Trolley jack for home maintenance, but on the road, AA,RAC or whatever recovery you care to use.
I wouldn't even think about using a jack out on the road.
TOO risky.

The pictures of the Kojack bracket show big wasers under the bolt head and hopefully there are similar washers under the nut on the other side. In both instaces of failure I have seen on Alko brackets the bolts have been used without any washers and the bolts have been very loose fit in the chassis and bracket holes meaning the contact area has been very small. Had the correct washers been fitted and the bolts correctly torqued, I doubt the brackeys would have failed. In both instances brackets had been fitted by supplying dealers.

You will see how big the original supplied washer are in this photo, not big enough IMO plus the brackets that I have, have slots machined into them so i got the largest washers available to sit into the bottom of the pressed bracket and hold the bolt central with the same size at the back below the nut and tourqed accordingly.

I'd like to thank Fatboy for starting this topic as I've learnt soo much from it (not too difficult as I'm a newby),
but as a result of the answers given I've saved myself nearly £100 by not now buying a jacking system I thought I needed.
I'm learning something new and useful almost every day by coming on,,thanks all.

Dusty,

I have just had a look at how the top plate is attached to the jack, only because i have an idea for an extension if needed to increase the height to locate into the jacking point without fouling the chassis ;) I think your brackets sit higher up than the ones I have fitted ?
