Sally -
There has been a LOT of discussion on this board about use of the jacks as jacks, vs stabilizers. A quick search on "stabilizer" will find most of it. The universal conclusion is just as Windy stated it - the jacks are indeed jacks, and are plenty strong to lift the TM bodily off the ground. Go for it!
The only remaining question is whether it is easier to pre-level the trailer by pulling it onto boards or Leggoblocks as Leon describes, or to simply park the TM at whatever angle the site presents, and then muscle it into level position using the jacks.
We will never come to universal agreement on that last question - and fortunately it doesn't matter! Both approaches are good. Like Leon, I don't like heavy lifting, so I use boards - no heavy lifting is ever involved. But other folks don't like the fussiness of prelevelling, so they opt for the muscle approach. Whichever floats your boat, as they say.
