Lots of reason why they get out of level. Ground movement, temperature changes, settling, jacks letting off a bit of pressure. I don't think I have ever owned an RV that didn't get a bit out of level after some time. Rigs with full walls slides can get out of level after a day just from having all that weight on one side - especially if you aren't on a paved surface. dramatically out of level could be indicative of an issue, but a little bit I would consider normal. Even stick and brick houses get out of level with settling and freeze/thaw cycles.

Hopefully the OP returns to the post.

Tough to get much easier than to hit the AutoLevel button, one and done.


Depends. The auto levelers on some RV's I've had operated like a Rube Goldberg machine and did some pretty funky stuff and often more than it really needed to. If wasn't already leveled to begin with not much of an issue, but since it was already leveled once doing it again with the slides out could extend jacks further than they need to be or some frame flexing etc. With the slides out that could be a problem. Manually bumping it a bit an inch or 2 on one side or on end is less dramatic than going through the whole auto level cycle.
I don't believe it will go through the whole leveling routine, just even out the level.

I would hesitate to do a Manual adjustment, as you don't know how much you've moved each leveler. On mine, you can adjust the front independently from the rear, but not one front independently of the other. And the rear independently side-to-side, but the center and rear both move together. Seems like it would be easy to get the trailer out of whack. Maybe level but not supported evenly. I'll stick to what works for me.

Manually leveling does NOT create binding of any type. If you hit AUTO the nose will dive and go thru the whole auto level process.

I quit auto level long ago as it's too hard on the system because I am VERY heavy.

"Manually leveling does NOT create binding of any type." And you know this how? Or just what you think? If you raise just the right rear side, which would be the middle and rear levelers, and not the front, what happens to the right front side? Won't it no longer be supported as much by the leveler at that corner?

I believe the hydraulic cylinders are rated at 8-10,000 lbs. EACH. So it would seem pretty unlikely you'll overload 50-60,000 lbs. worth of hydraulic cylinders. And can't see how manual level would be any different, the pressure is always the same.

I can't personally say whether it will recycle when AutoLevel, but have heard that it doesn't. But cannot say for sure, I've not done it when level so can't say.

I can tell when our trailer is out of level just by walking back to front. I'll just go to the panel and turn the system on and it will say "out of level". I hit auto level it does its thing and all is well and level. I try to not overthink things gets you into more trouble than out.

Ah, you can settle a disagreement: does the Autolevel go through its total cycle, or does it just move enough to relevel?

I know this because I have extensively had conversations with Melvin at Lippert on how the system works. The fronts adjust to what you do at the rear on each side. Have someone hit extend off door side rear you will see the off door front extend. The side levelers are tied together and balance them selves also.

The front drops when you hit auto level, you can't stop it. I guess all I can say that is how mine has worked in the past as I am not using auto again. So if you are slightly out of level after setting for a while go to manual mode and adjust to level it's that simple.

I would pull the slides in and retract the jacks and ensure the ground below the jacks is stable. Then put boards (or plastic pads) under the jacks to make sure the trailer is as stable as possible.

Over time the load on the jacks will cause some bypass in the cylinders. Mine does it every 4-6 months sitting in my barn on 5200 concrete.

Well, maybe yours does that, but my front levelers are completely independent of the center/rear levelers when in Manual. If I raise/lower the rear of the trailer, the center and rear levelers move, the fronts do not. It's best not assume that because yours works that way, "They all do that". [emoticon]

I don't know "Melvin at Lippert" but bad/wrong advice coming from the builder/factory is not unheard of.

I did NOT say the fronts were part of the rears but they DO adjust when the side is raised or lowered if they did not the frame would be in a twisted condition. Front legs equalize to the side by side created by the rears. We agree now?

The sides adjust to each other also so one is not supporting more than the other.
