My 2001 Fleetwood Revolution has an "Air Dump" button, which in fact dumps the compressed air out of the system. While I have been getting along well without using this feature, it must serve some purpose.

My question is - when should I use this feature?

Appreciate in advance your help. R1chy

My HWH auto leveling system dumps the air suspension before beginning the leveling process. I also have the option to manually dump the air without leveling the coach.

It gets rid of all that stale old air in the system and gives a better ride with fresh air in the bags

Kidding aside, the coach sets lower and makes the first step up to the entrance a little easier.

Richy,

Some leveling systems require you to dump the air manually before deploying the levelers. My Providence has Power Gear levelers, and the operators manual says to dump manually.

Dumping the air will get your rig closer to the ground, so that you don't have to extend the jacks as far. May also make your entry step more convenient to use. But if you are happy with the procedure you have been using, there is no real requirement to dump before leveling

Gary,

I was told by the service manager where I just bought my coach, that I would risk damaging the air bags if I did not dump the air before extending the jacks. Is this not the case after all?

I don't see any way that using the jacks could punish the air bags any more than driving down the highway does. Do you?
"
Some coaches with auto air leveling and/or auto air bag ride adjustment systems do need to be dumped so that the systems aren't countering each other, but if you have a typical, non-automatic air suspension I still feel that dumping is optional. Still, it is best to follow the instructions provided with your rig. Call Fleetwood for advice - RV dealers and Service Managers are not always well informed either. You might also check with the chassis manufacturer on the "damage the air bags" question. Remember, though, that any answers you get from official reps will always err on the safe side, where "safe" means least legal risk to the company giving advice.

Air bag dumping,

Have an 02 with HWH 610 , auto leveling system.

Never heard anything about damaging bags and dumping/ not dumping. Suggest you go to a more knowledgable service facility.

The above postings tell it all , so why be struggling with a high step if you can lower it by dumping?? Unless you are 7 feet 2 inches tall.

Thanks=== AIME===

I haven't heard of anyone causing damage by not dumping the air first when leveling. It's a moot point on my coach because the system will do it for me automatically if I don't air down manually. However, it occurs to me that if you don't lower the coach first and one of the jacks has to be raised further than normal that the weight of the suspension is going to be hanging from the the airbag or shock closest to that jack. I've been under my coach quite a bit and I haven't noticed any kind of restraints that would limit how far the coaches frame can be jacked up from where the airbags are attached on the axles.

As far as dumping air before or after leveling and opening slides , there is a very definite procedure of which comes first (at least on Monacos)– and it's in the manual. I'd list it here, but I have to go read it each time because I forget which is which.

All that said and done, I'm sitting here in Florida on a sand-base and getting slightly seasick from all the rocking back and forth. When I arrived, I went thru the prescribed steps for dumping (the air, that is) and for leveling and opening the slides, but my problem is that I keep sinking into the sand. All jacks are on concrete and/or wood blocks, but it isn't enough – every couple days I have to ˜tap' the levelers to get me back to a level stance again. What's happening is that it's putting more and more of the weight on the 3 jacks, and especially the front one – which is also the one that's sinking the most.

So, I got to thinking about how much more stable it feels when Wally-World camping (no jacks or deflating bags at all), and why can't I inflate the bags a bit more and put more of the weight onto the suspension and tires, and have essentially a 9-point (6 tires plus 3 jacks) level-system? I gave it a try, and it seems to be working better now.

Maybe a bit off-topic, but the heading caught my eye since I just finished leveling and thought it pertinent.

Ron

ronboc,
Your experience with having 3 jacks confirmed the reasoning that HWH uses in insisting that 4 jacks be used and installed where the frame maker says to have them installed. It spreads the load and assures that the frame doesn't go out of shape. No, I don't have any connection with them! But I always wondered about the 3 point jacking systems.

After my previous post, we just moved to another location and I noticed that the coach had split the 4 concrete blocks I had under the front jacks. That's probably why I had to keep re-leveling, as it split and then compressed the blocks and sand. Note these are the 16x6x4" solid blocks, not the ones with holes in 'em. And I'd put them down criss-crossed (2 facing front and 2 facing sideways) to spread-out the load. Guess the beer weighed too much

All that said and done, I still like the idea of 3 vs 4 jacks, as there's less tendency (theoretically, anyways) to twist the frame. I had a Class-C with 4 jacks and finally realized why I had to keep re-aligning the front-end after almost every outing - the 4 jacks had cookie-sheeted the frame. Supposedly the 3-jack system reduces this.

I'm with BIGRED1 on the possibility of a suspension-member hanging from an airbag, although the manual doesn't address it at all. On one of the first outings with our new coach, we were at a location that had a severe slant to the back. Noticing that a previous camper had conveniently left a couple 6x6 pieces of wood, I stuck 'em under the rear jacks and let the system level itself. When breaking camp, there sure was a lot of noise from the airbag-region as they re-situated themselves into their normal corrugated-looking shape. Made me realy cautious of trying to do that again.

Which brings up a general irritation ... Why do so many campsite developers leave tilted sites, when a lot of 'em could be graded better? I'm not talking about the rustic nature-encounter kind where we're waaaay out in the boonies on the side of a mountain, but more of the in-town type that simply another swipe of the bulldozer would have made it nice and smooth and flat. Maybe a gentle incline for water/rain drainage is understandable, but one that requires full-extension on the rear jacks plus 6" blocks on a site that was carved out of the open prairie is beyond me.

Maybe a few skyhooks, welded to some big eye-bolts?

We have gotten some good info on dumping the air prior to leveling. I try to reach a balance so the coach is lowered and yet I still have weight on the tires too. It is more stable.
Do we want to start a new thread on the pros and cons of three and four point leveling jack systems?
