Sorry, Newbie or not: HiLift Jacks are an accident waiting to happen. People get smacked in the face by the handles, pinched fingers and hands, vehicles fall off them and damage, if not human flesh then body panels. Their heavy and awkward to carry without special mounting and also require Hi Lift accessible hard points on your vehicle to use. They are unstable on almost any surface other than concrete or bitumen and most unmodified vehicles have nowhere to clip them into. Even modified vehicles with a Bullbar sporting a Hi Lift Jack hard point in the design still can't lift a rear wheel safely, so unless the vehicle also has a suitable after market rear-step/Tow Bar its still unsuited for all four corners of the vehicle.
Google Hi Lift Jacks and there lots of for, and against them. Personally and your mileage may well vary, I'll leave mine untouched in the corner of the garage. There are much safer (though I freely admit less convenient) alternatives to using a Hi Lift.
The OP should simply check to make sure there is fact somewhere to safely attach a Hi Lift jack onto his vehicle, and Google "Is Hi Lift Jack Safe" for a wide range of opinions and then decide on risk/benefit. If he can fit a Hi Lift and his risk/benefit decision is favour of buying one, the happy travels
BTW, I am obviously on the anti "Hi Lift Jack" side of the equation. It comes from my time in the Army many moons ago when we needed to Medivac a Digger who was smashed in the face by one of these things
(easy enough to do with muddy hands pumping a slippery pipe handle) They are now, and have been for a very long time, banned in the ADF.
