Sway on Jacks

I don't know if I am just being real picky or have a problem. I swear when we were camped in Texas and Tenn. before coming to Floida, I felt no sway or movement of the rig on the jacks. Now no matter if they are just barely down(rig level) or fully extended the motorhome will sway, especially when coming in or going out of the door. Think sometimes the coffee is going to slop right out of the pot. I called Power Gear and they told me what to check, retracted the jacks, checked the fluid level and found I was about 1 1/2 qts low. So filled it to the correct level, extended the jacks retracted them again to check sensors, still shows jacks down. Extended them again and leveled the motorhome, put a piece of tape on each ram 1 inch from the cylinder, to check to see if they were collapsing while the wife moved around, nothing changed. So guessing my jacks aren't the problem. Could the shocks on the rig be wore to the point they are allowing the problem. It's just aggravating and I hate that I can't roll over in bed without the rig moving. Any ideas. Thinking about getting a set of the screw up jacks and see if they will stop it.

I don't know exactly how much movement your feeling but it sounds like quite a bit.Some movement is normal.

I am not sure if you are trying to level on uneven ground, but I typically use blocks under the jack pads so the jacks are not extended as far. I find that the shorter extension keeps the rig more stable. I used two 12"x12" 1/2" thick plywood screwed together as my jack bases. Happy Camping.

Sitting on 4 inch+ concrete pad. Only have the jacks extended maybe 1/4 of their length. Just enough to level the rig...

Try 1/3 to 1/2 pad extension. Leaves enough on the suspension to help stabilize.
No wheels off the ground.

I don't know. When I extend all four jacks for stabilization purposes, I still have movement when people walk about. It has never been rock solid.

How could it be the shocks if "up" on jacks? They should be completely out of the loop. I'm betting on the "picky" problem

There will always be a slight movement unless you lift the RV completely off the suspension and set the chassis on concrete blocks.

if I do just enough to level and the padvis pretty level I get more movement fix is to extend further and take the coach more off the suspension.

Have you tried to level the unit manually, that way you can put a little more pressure on jacks.

Just my musing; Parked on level concrete pad, used automatic leveling,(are air bags fully deflated?) jacks extended enough to obtain level. IMO this means the jacks extended to barely touching the concrete, sensed level and shut off.
CampDaven's suggestion might be the solution.

My rig don't have airbags. I have ran the jacks all the way up, to the point of lifting the rig off the ground. My rig doesn't have auto leveling, just manual. I have checked to see if I have a broken mount, didn't find any. Maybe as some of said, I am too picky, I just don't remember the rig swaying or moving as much as it does now while we were in Texas or Tenn this past spring and summer. Will keep experimenting, maybe I will hit upon the cause...

You will get the most wobble if the jacks are too high or too low.

Try 1/3 to 1/2 jack extension. Leaves enough weight on the suspension to help stabilize.
