Hi All
I've had a Kojack for a few weeks now. What a great device. I purchased it to level my caravan on a seasonal pitch, as it had sunk on the one side enough to stop the water in my sink from draining away ! Took about five minutes to fit the attachments to the chassis, and then another five minutes to jack the caravan up and stick some chocks under. The longest time I took was to find the right sized spanned and socket to tighten the attachments ! They fit brilliantly, and are very solid.
My only gripe was that I needed to detach and lower the spare wheel carrier to make room for the jack under the jacking point, although you'd do this if you were unfortunate to have to change the wheel.
The spirit levels on the newly attached jacking attachments were useful, although the "left to right" levels were more difficult to read given their locations.
Yet to be seen how weather resistant the new jacking points and their four attached spirit levels will be if you left them on all the time. I'd be inclined to bolt the jacking points on when I needed them, and keep them safe in the caravan. Just ensure you have the spanners.
However a great piece of kit with effortless results and well worth the 50 quid !!
Cheers
