yes you will feel alot of rocking without any type of stabs. I would invest in some scissor stabs. You can see if you can special order the "AXIS" that you like with levelers. THOR is huge, and a big part of THOR driveables come standard with LCI (Lippert) 4 point hyd. levelers. I would bet your dealer would be happy to special order one for you.
You can have an LCI added, but I found the add on systems tend to be more troublesome. I would either add scissors to the one you are looking at, or special order a new unit.
