Our first trip in our rig I noticed the hydraulic slide acting sluggish. I checked the oil level with jacks up and slides in. The reservoir was not quite 1/2 full. I picked up a small hand pump and a couple of quarts of full synthetic ATF. I removed the remaining fluid and filled with the synthetic ATF. Never had any popping like I did in my last rig.
If y’all don’t want to go that route you can get Anti Stiction additive on Amazon.

I do give them a A for effort as they sent Lippert service reps to AZ twice and MN twice but turned to an F when they gave up. Popping etc made trailer jerk as pressure was lost. When we where gone during Covid AZ park it was in called and said trailer was about to tip over. We had to send local repair guy to re-level for $100.
Yeah. Well, I seem to remember quite a few threads about similar issues that led me to try CAT. Seems it had a pretty good success rate. You just need to swap out a small amount of Lippert juice for CAT. Anyway, wish you some success.
I'm a former rv service manager and Marina owner. Most of these companies know less than we do. It would take hours to list the repairs I've made on our 2019 DRV. The previous owner gave up and traded after a year. As for CAT fluid it stopped all but one jack from popping, and now it's only occasional, they all were and continuously at times. We're currently in a park and haven't cycled it many times since I added it. We have 4 slides and are over 42' so there's a lot of lines and fluid. I Was barely able to get a quart in without removing any. I read multiple replies that it took more than one so I bought two, will add the other when we get home.
As for your issue.Your issue with the jacks collapsing, if the CAT fluid doesn't cure it replacing the electric solenoid for the corresponding jack(s) will, I'll bet on it. Been there done it with our previous Big Country. Make sure you're not loosing any fluid, mark the tank with a line with everything retracted and in, a leak will cause it also, could even be in the belly of the coach, I had more than ten loose fittings.
CAT didn't, motorcycle fork oil didn't, ATF didn't and 2 other unknown Lippert concoctions didn't, Solenoid didn't, replacing 6 jacks didn't, replacing fronts a second time didn't. Been to authorized dealer twice (one for over a month in summer) and had 4 differnt Lippert factory techs out 4 times as well as 2 RV repair people we paid to look at it. Most frustrating thing I have EVER dealt with and going on since install in 2014. no leaks as fluid level is always constent.
