Welcome to TT ownership, and that sure sounds like an ambitious trip you have planned! You are lucky to have such a heavy duty rig to tow it. Our F150 does OK 99% of the time.
As far as making the jacks independent.....get some plastic jacking blocks, run the jacks together close to the ground, the see which one is a little further away. Place a block or two under there, run both sides down, and you are done. It's really pretty fast and easy.
