I have a 2022 Allegro Open Road 34PA and my two front slides are creeping out and leveling jacks creep down. This is not an HWH system, Tiffin went with Lippert for 2022 Open Road.
Dealer has replaced hydraulic pump but still does it, they claim solenoids are good but I have my doughts!
Anybody else with a 2022 have any problems? And does anybody have any ideas?

Have you discussed with Tiffin tech support directly? If not, suggest to do so.

The Lippert slide creep is a hot topic on the Facebook Tiffin Open Road forum. Lots of thoughts as to the cause but no solution as of yet. Have it on my '22 34PA. I contacted Tiffin and they took my VIN # to log the issue. Will also contact Lippert. Several folks that have contacted Lippert stated that Lippert rep acts as if they've never heard of this issue before.

Could also be trapped air from improper bleeding.

My slide creeping out ended up being the two valves inside the cylinder failing. Since they were internal there was no leakage to see outside of the system. I did the process to rid the system of air a few times, but that wasn’t the root problem. The tech removed the hydraulic cylinder/ram and took it to a hydraulic shop for testing. They can test and tell pretty quickly. They opened up and replaced the valves the same day and we reinstalled the next. Cost me $180 versus possibly weeks or months waiting for a new one given supply chain issues.

Talked to tiffin today. They said there was a change in the connection from compression fitting to o ring on the Lippert. He said they were over tightening and crushing the o ring.

Change is good, right??? wonder if moving to the Lippert from the HWH is pat of the new Thor ownership, looking for ways to cut cost and increase profit? I love the Tiffin product line, but if I was in the market right now, I think Id hesitate on buying new until things sort out with the new ownership and production process.

My new 2022 Tiffin Allegro Open Road 34PA has experienced hydraulic slide drift from day one. Usually 4-6 inches and so far only while in storage. It's a Lippert hydraulic system.
** There is a May 31 2022 recall for this exact issue and today my dealer ordered those new cylinders. In the meantime, I'm shopping for slide "locks" to manually stop this.

Incidentally, an entire Lippert hydraulic pump was also ordered under warranty due to leaks. I now keep a flat moving box with bricks beneath it to catch fluid.
Further; one slide extends while jacks are auto-leveling, retracts while jacks retract. The other slide extends while the first is being extended.

These hydraulic systems are messy, unreliable and often break down.

I have a 2022 34pa and am in Red Bay right now for warranty work and they changed my cylinders last week, have been fighting the creeping slides for a year. Do not put slide locks on as they will damage your slides if they creep.
The hydraulic pressure is too great and will bend a the locks and damage your slides.

I too have a 2022 34PA and googled the same issue, leading me here. If parked level, I have a slow creep of 2" max. If off level and stored, it creeps out pretty good on passenger side front.

Fredtp, just a question of clarification, when you say the jacks creep down, is that from their full up position, (retracted) position? Or is the coach setting on the jacks and they retract slightly from the leveled (extended) position?
Are your jacks two way hydraulic operation or are they one way hydraulic and spring return?
