Not sure if I have done the right thing but I obtained some 3mm thick and 50x25mm square section steel tubing from ebay and drilled holes at 55mm apart and fitted these sections to my caravan chassis as jacking points.
I measured and cut the square section steel so it sticks out below the chassis by about 20mm and jack from there with my own perfectly adequate bottle jack and a improvised 'cup' to fit under the square section and distribute the load.
I fitted them directly using 12mm high tensile steel bolts with nylock nuts. All in costs under £10.
I know there were some good offers for various other lifiting devices around before now but could not find one and did not want to spend £60+ on the alternatives...
Happy to post pics if people interested.
Chris
