With that said... scissor jacks really shouldn't be used to 'level' your rig either.
You should start off by leveling best you can side to side with leveling blocks under the tires/wheels. Then use your tongue jack (or landing jacks if 5th wheel) to level best you can front to rear. Then use the scissor jacks to fine tune.
If you are too far out of level to begin with and utilize only the scissor jacks to level, there is the possibility of frame twist or damage.
Above is the entire process to level a vehicle or trailer. Two steps. Any departure is unnecessary and using jacks at each corner only puts the unit on a bind at the least, or bends the frame at worst.
1. Back onto boards or legos, until low side is level SIDE TO SIDE. You may have to back on and off scraping or filling the spot until that side is exactly where you want it. This is STILL step one.
2. With slides in, and stabilizing jacks up, adjust tongue jack until level front to back. Now drop stabilizing jacks and extend slides.
Chasing a level by going from one corner to the other is frustrating, unneeded, and only results in spoiling an otherwise end to a nice day.
