Both slides pop out.
I have a technical question. Not sure if this the correct place or not. Yesterday i hooked up to my 351M. I retracted both middle slides, hit the “hitch height” on the leveling controller. Once it went through the process of retracting the jacks, both middle slide popped out about 6”. I went inside and retracted again. Then I hooked up my truck and retracted the front landing gear. The slides popped out a second time. This is the first time this has happened to me. Only owned this for about 2 months. Any ideas what is happening. Seems like it could be a valve that needs adjusting. Thanks.

That is definitely not normal. I would give your dealer, GD Customer Service, or Lippert a call.

My 2021 351m does that sometime after I hitch but only about one to one and a half inches. I close them and they stay after that. Does not do that every time.

There is a leaking check valve somewhere, or, there is air in the lines.

The valve that is causing your hydraulic slides to extend a little is called a Hydac valve.. there is only one for all the hydraulic slides .. this is easy to change if it is failing
It is NC ( normally closed ) via an internal spring on the needle valve and is electrically opened via a solenoid mounted over the Hydac valve..
Also..Mon the top of the Hydac valve is a manual override screw,,p if this is not closed all the way it will allow some fluid flow this causing the slides to partially extend
