High Lift Jacks and Air Bags.

I have an exhaust /air bag my personal experiance is that they are great in sand and mud as they have a much widder base in the soft stuff where a high lift or normal bottle jack will sink without a good base board , the air bag is the best way to lift up a caravan as they can tend to slip off the standard bottle jack if you get any movement, I find them very quick and easy to use ,the only trouble I have encountered is they can be a pain to get back in the origional bag so I have had a bag made to measure with a zip full length , this is just my experiance hope it helps ( air bags are lighter to )

Hi Lift are very universal tool, with the capability of using it as a winch but it can be a little dangerious. The air bags are a pain if they get a hole!
Keeping the hi lift out of the weather is a must any rust they need WD spray. Buy a Hi Lift or Jackall not any other they are of lesser quality.Good Luck Jol

There would be no problem with the internal air bag, takes a lot to set them off, i wouldnt be concerned, do a lot with 4wd training
