My guess is that a boy named SUE was working on it (Stupid USER Error)

The rule is you may lift ONE and only ONE FRONT and only the FRONT wheel off the ground safely.. However there are conditions where you might lift more.. For example if you are changing tires. INSIDE a wind protected shop.

My guess is he jacked it up so he could crawl under it to work on something.. I must admit I work under my rig on occasion with out a hoist.

But then the only place under my rig I can not crawl, JACKS RETRACTED, is under the differential pig.. Even the front axle has enough ground clearance (Though i would rather go around on that as well) But that is my rig.

BigD9 - The way I've been doing it, I put the rear jacks down, then level side to side by tweeking the rear jacks after I put the fronts down (for front to back leveling)... Again, I usually only put the rears down to a point where I see the back move slightly. My test for level (other than a level), is to see if the bathroom door stays in place when you open it. Sounds kind of primitive, but it works pretty well... I see you have a Discovery as well and will try your way next time, which will be next weekend.

The only time our rigs tires are off the ground is when changing a tire. If the site we have would need the tires to be off the ground for level, then I either use 2x12 pads or change sites.

If there are coaches whose air bags can extend beyond their normal limits and support the weight of even a front axle when the wheels are off the ground, I’ve not seen one. On a rear axle, it seems even less likely to be possible. When the bags are fully DEFLATED, all that I have seen have internal stops, so that is not a problem.

On all the Monaco’s I have seen, the shocks extend to their limits and it is the shocks actually supporting the weight. Even that seems like really bad practice, and it is surprising to me that the shocks can survive it. Of course, there is the fact that Monaco’s have a high incidence of upper shock mount failures, and I have always suspected it was the result of lifting wheels off the ground with the jacks, NOT normal stresses from the shock absorber.

I have seen three instances of owners attaching four supports to the H-frames, front and rear, to support that huge weight when the jacks lift the wheels off the ground. Two owners attached chains inside rubber hose, and one used a heavy tow strap type of material. If one had these supports, using the jacks to raise the coach’s wheels off the ground for service seems to me an OK practice. But I would not suspend my own on only the shocks. And bear in mind what others have said—you only have “parking brakes” on the rear.

Push AUTO

So much conversation! Just push the AUTO level button after the test cycle is complete. 99% of the time, you will be level in about 2 minutes.

Well.. PUSH AUTO... only works if you have an AUTO to push (I do not).

I will explain a bit As someone said if you have air brakes then the spring brakes (parking) work only on the rear,, If you have Hydraulic then if you have automotive type parking brakes they work only on the rear wheels, My RV (Class A) has a drive shaft brake so it only works on the rear wheels. but wait there is more.

With a dirve shaft brake if you lift even ONE rear wheel off the ground the rig can move foreward or backward, turning your nice lovely hydrauilc jacks into roughly thousand dollar EACH pretzles.

And if you lift both wheels on the same axle off the ground a gust of wind such as hit my motor home last night and .. Same thing.

(You know that old sign.. "If the rig's a rockin' don't come knockin' " well last night it was really rocking, but I'm all alone in here.. Bit of breeze was shaking it)

They said it hangs the weight of the front on the airbags.
Nope!

Unless I was parked on a sheet of glass, I have no problems in lifting whatever wheels off the ground as necessary to get the coach level. Of course my preference is to raise the front rather than the back, but that isn't always possible.

This controversial subject can quickly be solve by this question.

Has anyone damaged their front suspension or coach by lifting their front wheels of the ground with their jacks?

Speak now of forever hold you peace.

Lift All Wheels!

I can lift any combination of wheels off the ground. Just use chocks if your concerned.
