Over the years I have worked out a few was to use jacks and Hi-Lift Jacks, If I can't get a normal jack under there I will use the Hi-Lift to raise the body enough IE jacking off the Tow Hitch but not taking the Vehicle off the ground and then putting the Bottle or scissor jack or Trolley jack under there so it is just taking enough weight so it can't be pulled out and then remove the Hi-Lift and then raise the vehicle and if the ground is good then placing an axle stand under there, It's a long winded why of doing things but some times a Hi-Lift is not the right tool and some times it is.
Thing is a Hi-Lift has saved my Bacon more than once, It helped me raise up a Horse box once so I could get it up on stands when the Axles were to low to place a jack under it and it also served as a 3rd safety point along with the axles stands and the Trolley Jack. Problems start to happen because people do not use these things enough so they become blind to the dangers of what might happen, The more you use them the more competent you become with them, See the dangers and know the dangers and use the thing, Once you master them you will not have any problems,
People buy these things and have a play with them on the day it arrives and then can't wait to bolt it on their Truck or jeep to complete the picture and there it stays for 3 or 4 years until they need it and they are doing their practice out in the field and then Cuss out the Jack when things go wrong. People need to learn all this stuff while they are at home not out in the field, A simple cure for this is unbolt ya Jack clean it service it and put it through it's paces and Oil it back up and once you have practiced with it then put it back on your truck, Keep your fingers off the main upright and always lock the handle in the upright position and Keep your head out of the Arc of the Handle and stop every so often to check the jacks position and stability,
Don't use the jack it a straight vertical position, you want the Base slightly inwards towards the truck compared to where the Top is because as the Jack raises the Vehicle the jack will lean towards the vehicle, If you place the Jack perfectly vertical as it lifts the Truck it will then lean at an Angle towards the truck and then as you raise it more it will be leaning up to 6 to 8" towards the truck That's when it is about to slip off the Jack, SO first line the Jack up perfectly vertical and then Kick the Base in by about 3 to 4 inches and when you have jacked up the Truck it should be just about perfect.
hope that helps.
