There will be movement due to trailer being mounted on tires & springs.
You can get the add-ons mentioned....
Just curious it being your 1st 5vr 'How are you setting up'?
We don't have any of the add-ons and movement is very minimal.
After unhooking from truck I run front landing gear (up/down) to level rig front to rear (I try to minimize how much inner tubes are dropped).........then lower front 1"
I then run rear stabilizers down using 6"X6" blocks under the stabilizer pads so that they extend as little as possible (wider stance---more stable).
I set rear stabilizers tight.
Then run front landing gear back up to level.
Been doing this for almost 7 yrs. of FT and rig sits pretty tight with just minimal bounce.....so minimal when rarely notice it.
