I have the 3600 - Ultimate Trailer Gear duffel bag that has all the Andersen gear you'd need.
However I have not had the need to use the Andersen Jack that is in the set.
As for using the Andersen levelers though, I'll never be without them. Used to camp a lot with my parents, and we used the old method of "throw down a couple of boards and see" when leveling.
With these I can be level in less than 5 min without any help.
I'll report back if I have a chance to test the Jack in the next few days. But the suspension does have quite a it of travel on this TT.
