DIY Air Bag Levelers

I don't mean the type that are attached to the Bus, but a flat bag that you place under your tires and fill with air. It would replace the boards that you drive up on. I've been researching leveling the beastie while parked. Not exactly cheap but the idea of not having to carry around all the "firewood" sounds attractive. Might make a nice project for this winter.

The following links are a mixture of You Tube videos, posts on forums and pictures.
]How to make airbags for leveling an RV on an uneven campground. [/url]They are intended for tandem axle trailers but may be suited to other applications.

The hose you need for the project is 8" ID Medium Duty Lay Flat Discharge Hose. It's available from McMaster-Carr, part #5310K49.

Expect this project to cost about $100. (for two bags lms)

The user, mike_mn, on RV.Net details this method in a popular post. Many thanks to him for sharing the method. I hope I've improved upon it slightly.

Here is a link to his post:
http://www.rv.net/forum/index.cfm/fu...rt/pa/pging...

A company called Levelair used to make bags like this, but they are no longer in business. The user, abeand, on RV.Net says he owned the company. There is another company still making a similar product - it's very expensive.

Re: DIY Air Bag Levelers

Good post Lorna. I see that one guy has tested to at least 8500 lps. That should be adiquate for even the heaviest of buses.

Re: DIY Air Bag Levelers

I don't see why not.One under each tire is 8500 x 6 = 51,000 #s. Rear axle 34,000 front 17,000.
Air bags are used all the time in heavy duty wreck recovery, many times to set a trailer up WITHOUT unloading it.

They are also used to lift aircraft,http://www.aircraft-recovery.co.uk/AIRRS.htm

Re: DIY Air Bag Levelers

I've been scrolling backwards through the posts, and after seeing this post, am very happy I decided to do so! Great idea. The video was very well done.
Thanks for posting this gem, Lorna.

Re: DIY Air Bag Levelers

i will add this to my list of stuff to make. If i knew how easy they were to make, i would have made them years ago. I even have left over discharge hose from the water tanker for fires.
These would make great jacks for some purposes, they can be teamed up and stacked for larger loads and height..and they won't cost $50 apiece to make...
I do all my own tires also, so cores, cement isn't a big deal for anyone as all that stuff is available at the auto parts and the tire stores.
Hose length isn't important, they can be longer than in the video.
I would think making up a dozen or so at the same time would be a good idea. One could also put them between blocks and use them for jacks..doesn't have to be under the tire.
For those busses that have air suspension like mine, one can make up or buy the leveling systems using you air bags.

Re: DIY Air Bag Levelers

Thanks TygerCub for bumping this thread, I didn't see it the first time around. My first thought was that this was a lame idea, then I watched the video. It's a great idea!
