Strange, both rams work on the same pump pressure and manifold back pressure. The rods always have locking pressure on both sides of the piston except when the valve opens and unbalances the circuit. You can try to move the nylok nut tighter on the outboard bracket to move the room in a bit closer in the front. The way the piston rods float on brackets it may hold. The rattle won't go away unless you put thin bushings over the piston rods threads where passing through the rough cut guides. There's lots of slack in there, again part of which will allow for misalingment when the room is in motion. You may be able to stop the creep by checking and tightening the valve on the pump manifold for the slide. In this case its closest to the front on the outboard side

Sounds like maybe that particular piston is leaking around inside and reducing the pressure on one side. I have heard of pistons doing this.
In this cae no adjustment can correct and you need to see a dealer and have that piston check.

Thanks for the suggestions. I think I'll try tightening the nylock nut a little and checking the manifold valve. The only downside seems to be the rattle.

Does anyone else notice a sharp metallic rattle on rough roads? Or, are there too may other rattles to notice?

Just a thought. You have a fireplace don't you.
I had a rattle when driving and it was the glass front that was rattling in the frame. My DW put q-tips between the glass and frame until we got home.
Then I removed the glass and put rubber electric tape all around the glass edge and reinstalled and no more rattle.

Maybe that is your rattle? Go and push the front glass around and see.

We had that kind of rattle and it was driving me nuts. One day asked DW to go back to the kitchen when we were on a somewhat bumpy road. It was the lid of a china tea pot. We never heard that in the fifth wheel. Just one of the new thinks going from a fifth wheel to a motorcoach.

Iggy - Thanks for the suggestion, but we had to have the dealer fix that one before we would take delivery! Current rattle sounds different, but from about the same location.

The shower door is pretty noisy too, sounds like the city bus. Don't think there is a way to quiet it down.

Yes -some people don't realize it, but a hydraulic cylinder can and sometimes does leaks internally. The seal (s) on the inner cylinder will leak and by pass fluid from one side to the other. If you can get close enought to listen (not sure if you can do that here) and there is enought pump pressure you can sometimes hear the fluid by passing. If the other seals are tight enought, you will not usually have any external fluid leakage.

As stated by Iggy, a dealer or repair shop shoukd be able to bench check the cylinder for internal fluid by passing.
