We don't have the scissor jacks, as our TM is older, but what we use is a magnetic 8" torpedo bubble level that rides along with us on the front of the battery tray, under the battery strap. It's amazing, it's been thousands of miles like that and is still there today.

We use leveling blocks under the wheels to level it side to side first. These sometimes aren't needed in paved RV parks, but in rustic parks they are a must. We back in, check the level on the tongue (the bubble level is magnetic, so we just put it on there straddling one of the tongue pieces, sideways), and then add a lego block or 2 to the low side, usually pull forward and then put the block down and back onto it again. After a while, you get to know how many it will take. It's not an exact science, but an inch or two or three makes a difference.

After that, we switch direction on the bubble level front to back and crank the tongue jack to where it needs to be.

We just use the jacks to keep the TM from moving around when we walk around inside and step in and out.
