I did not read the whole thread, so I might be off track here.
you are on dirt and the jack is too tall to fit , dig a hole and put it in it. If the jack is sinking into the ground put a bigger base under it (you should do this anyway for safety), doesn't have to be 2x12 lumber, can be 1/2" steel plate or any thing strong enough to handle the load and will fit (increasing the size of the base enough, decreases the load psi on the soil so it will not sink...10,000 lb load on a 5"x5" base = 10,000/ 25 sq in = 400 psi......10,000 lb load on a 10"x10" base = 10,000/ 100 sq in = 100 psi......distributes the load over a larger area
Technically, on dirt, it is possible to put the jack under the tire (not recommended) or any suitable part of the suspension and jack it up .... If you are going to dig under the tire, block up the vehicle first, then... dig out enough under the suspension to get in the base plate and jack plus room to operate the jack handle. Raise, block, repeat until you have the desired height. Make sure it is blocked at all times for safety.... more is better. Blocks also need large bases and don't forget to set the brakes and chock the tires. Many people die every year from vehicles falling on them. I've known 2 personally.
I saw a guy get all 4 wheels stole with out using a jack. The thief put concrete blocks under the suspension, removed the lugs, removed the cores from the air valves, loaded up and hauled ass. Probable stole the blocks he used/left too.
