Hi,
went to a club weekend some months ago, where the more experienced members showed some of us newbie types the 'how and why' on winching, tyre changing and various jacks, high-lift and exhaust included.
It was shown that if you want to lift the vehicle to the heights obtainable with those two tools, you must plan for some instability, especially if both wheels on an axle leave the ground.
I only have a couple of bottle jacks, and am not sure if a high-lift is any use to me with a slide-on camper on the tray, I just can't get the jack close enough to the body to get a lift.
It fits the ARB bar ok, but unless I design something into the rear of the next tray I get that will accept the high-lift, I doubt I will get one.
The exhaust jack just looks scary, and I wonder if it can be used on the rear of a cab-chassis with all the bare metal work there any way. Looks WAY too prickly for an inflated bag to press against, even with padding.
cheers
