Just throwing this out as far as bottle jacks. If you already have say a 20 ton or 12 ton jack, great ... if you are buying ... all you really need is say 6 ton. Just because your fiver weighs 14K doesn't mean you'll be lifting anywhere near that should you place the jack in-between the spring UBolts. I used a load cell atop my bottle jack once while lifting one tire on my 3150 about an inch off the ground simulating a tire change. @ 2800 lbs. The rest of the fiver weight was sitting on the other 3 tires and front landing gear. I will admit ... the bigger the jack, the easier to pump, but 6T works for me.
