With our TT we would put the TT exactly where wanted. I would then put the level on the floor inside the door and see if its level. With experience and by looking at the level, you will learn how much lift on the side you will need. We would place boards or leveling blocks beside the tires that need to be raised. I would pull the TT far enough forward or backwards and move the boards/blocks in place where the tires were. Then move he TT back up on them boards/blocks. Recheck for level. Once level, we would put plastic chock in front of and behind the tires. Unhook the TV and level front to rear with the electric tongue jack and using e level on the floor again. We then would place x chocks between the wheels and lower the stabilizers with 6x6 wood underneath each one to not extend the stabilizers to far out. After a while, usually before bed or the next morning, I would have to tighten down stabilizers again.
