This is my response to post 18
You should never remove a jack from the vehicle except to change a wheel, funny thing is people go and buy extra spare wheels and all the you beaut 4x4 gear and over look a 2nd jack.(not counting the high lift) Most times jacks do not work because of no maintenance or lack of use, so a trip to your wrecker can normally buy a cheep jack to suit your vehicle or you could buy a jack anywhere as a back up to your main one they are not that dear. I have a $35.00 hyd as a spare just in case in my 2wd hilux. I know of people that have driven off leaving the jack behind after a wheel change.
I also think a lot of 4x4 gear fitted to a vehicle is just more things to break, a winch for example should only be used to get out of a bad situation not to get yourself into one. People say I can get through that I have a winch instead of finding another way and half through the winch fails. It does happen. I meet a fella that had a nice shiny high lift jack an an even better 4wd wagon that had nowhere to place the jack if needed without doing damage to the vehicle, when I said this to him he said their must be somewhere everybody else has them. What I am saying is you can have all the gear you want but you should stick to what you need and what you have the ability to use correctly and safely that last thing you want is a break down or an accident.
This is only my 2 cents worth and I am not having ago at the experience 4 wheel drivers that know their stuff.
