I take it you will be investing in a trolly, bottle or screw jack for day to day maintenance then as a Hi-Lift (or similar) jack is a recovery tool and occasionally a only a workshop tool as far as LR's are concerned? Fine for lifting & slewing the vehicle, good for lifting the chassis nice & high prior to using axle-stands to carry out underside maintenance but for day to day maintenance they are potentially unsafe due to their inherrent lack of stability. In addition, why bother lifting the chassis and waiting for the springs to extend before a wheel lifts off the floor when a conventional jack lifting under the axle will raise a wheel in just a few seconds?
Don't get me wrong, I have owned a genuine Hi-Lift for nearly 20-years but it spends most of its life in the shed as on the vehicle it would just be ballast. In the wrong hands, used incorrectly or not maintained properly they are dangerous things (a friend of mine had to spend time in hospital after a Hi-Lift handle caught him a lovely one across the head) and most of the time they are just not necessary.
