You should check the unit as some Monacos of that era had both hydraulic and air leveling. Mr. Mark has the best system. His Liberty comes with a butler that does all the work!

Yep, that would be me..... butler, chauffeur, fuel attendant, washer/detailer, head cook/griller, etc. :R

I wear a lot of different hats!

No. YES The Monaco came with hydraulic leveling jacks or the "upgraded" air leveling system. This has the air system, no jacks. Much to my surprise, once level it is rock solid!

My rig has no jacks. Why did you imply it does?

I quoted the wrong post. Settle down....:R

I think you will find that the Camelot has a Valid/Power Gear air leveling system. Disregard most of the replies if that is correct as the 2 systems work differently. We have that system in our Dynasty and my BIL has an 09 Camelot and it has the same system. When parking you just hit the "Auto" button and the coach levels itself. It does not dunp the air and then re-level. These are not some gas model lightweight MH's. They are darn heavy and you get very little movement. One big plus with air leveling is that you are not twisting the chassis and popping windshields. You should check the unit as some Monacos of that era had both hydraulic and air leveling.

Our CC has the HWH air leveling system only, no jacks. I've tried it both ways.... first dump air to let the suspension lower, then activate the air leveling, or just start the air leveling while the coach is still at ride height.

Bottom line, I don't seem much difference between the two in terms of where the coach ends up but dumping air first seems to prolong the process.

As far as movement, I don't see much difference in normal use from that of our previous coach with hydraulic jacks. Now recently we were parked with sustained 40 mph winds hitting the coach broadside, with 60 mph gusts. It shook the coach. Only time I wish I had jacks to provide some additional stability.

I did not like air leveling as even 15 tons coach will move with 100lb person walking around.
And if at any doubt - read the manual.
Too many variations in design to apply procedure from one system to another.
I remember practical advise for tilting jacks to move them to vertical position before dumping the air.
When you set the coach too low before tilting jack, they can hit the ground at angle with bad consequences.
Always check the jacks around before lifting.

Our previous '08 Dynasty had air leveling AND hydraulic level legs. Both had slight movement.... If I didn't know, I couldn't tell which one was being used, they both would move a little when someone walked through.

The new coach is air leveling only. At 55,500 lbs., we also have a little movement.

Just to add to what Dennis explained very well.

The first step the HWH does in leveling is to release air to achieve level.

If, and only if, the HWH brain cannot level the coach by exhausting air, then it will cause the aux compressor to come on and the brain will inflate air bags to raise a side or end of the coach.

Because the HWH brain exhausts air first, you will find on almost all cases that the step is as low to the ground as it can be for the site you are parked on. Much lower than a jack based system.

This is what I was hoping. Thank you!

We have both HWH air leveling and RVA hydraulic jacks. We have been on air for 6 weeks. I ran the coach once to replenish the air tanks, but wasn't below 60#. It isn't quite rock-steady but most of the time you can't tell that it is not on the jacks.
On our coach we turn off the ignition, dunp air manually and then auto level with either system. Both systems will make minor adjustments for about 30 minutes after turning on, then I turn them off to avoid any 12V drain.

The HWH air leveling system logic assumes that you start at ride height. That is where the manual says to start. You can dump the air first, but, you may limit the ability of the system to level.

Think of it this way, for discussion, that each air bag can raise or lower 6" from ride height. With the back full down and the front full up you can level 12" across the length of the MH. If you dump then only one end can go up 6", instead of 12" of both ends moving.
