Air suspension for motorhome

The standard suspension installed in campers and camping vehicles can bear heavy loads. However, to ride more comfortably and feel more confident in corners, you can easily improve it without spending millions.

This is one of the reasons why I decided to install pneumatic cushions in our camper.

While writing this article, I have already completed the first 6,000 km, during which I had the opportunity to check the advantages of this solution.

Stable in corners

What can be felt most after installation is much better stability when cornering. Our camper is charged to its limits all the time, and sometimes I even exceed that limit.

Therefore, I had to slow down very much on bends and roundabouts, because the vehicle tended to tilt quite a lot. Now I can inflate the air springs, which makes the suspension harder and the rocking stops.

Hard or soft suspension

I adjust the airbag inflation level manually using two buttons located on the steering wheel. Importantly, I can make this adjustment even while driving to quickly select the appropriate pressure to obtain the best comfort or type of surface.

If I'm driving on a rather potholed road, I let out some air and the suspension becomes softer, I can better absorb the bumps and the camper doesn't jump. On highways and roads with good surfaces, I increase the pressure and the suspension becomes harder. This virtually eliminates the side gust felt when overtaking trucks.

On the indicators, I can see the pressure at which the cushions are currently inflated, which allows me to quickly set the appropriate level.

Leveling and stabilizing the camper when parked

The cushions are only installed in the rear suspension, which allows me to slightly maneuver the rear of the camper up or down. Thanks to this, I was often able to give up taking out the ramps from the garage to level the camper. All I had to do was release the air from the cushions, which lowered the rear of the camper by about 10 cm - it may not be much, but in most cases it is enough.

In addition to leveling, we can also stabilize the camper when parked. By inflating the cushions to 6 bar, we will stiffen the rear suspension appropriately so that it does not swing too much when stationary.

This solution will not replace the hydraulic supports that we had the opportunity to test in campers with a GVW above 3.5t, but in many cases it will be sufficient.

Importantly, I can independently adjust the height of the left or right side, which makes leveling much easier.

Inflating wheels and inflatable toys

I have a two-piston compressor installed, which is located in the entrance threshold to the driver's position.

A great solution is the ability to connect a gun with a barometer, which allows you to inflate vehicle tires or what is most useful when camping with children - inflating inflatable toys. I even bought an appropriate adapter for SUPA and I no longer have to pump the pump for 15 minutes in 30-degree heat.

Inflating is not very fast, but it definitely makes it easier - to inflate SUPA, the compressor must run for about 15 minutes to obtain the appropriate pressure.

Purchase and installation

To sum up, I am very satisfied with the air suspension and I will equip it in every camper I will drive for a long time.

The suspension was purchased and installed by MTT System from Gliwice , which is a 100% Polish company and all production takes place on site. This allows for quick order fulfillment and constant availability of spare parts.

The company is constantly developing its network of partners throughout Europe, where you can purchase and install their suspensions - all information on this subject can be found on their website www.mttsystem.pl .

MTT System has suspensions for all delivery vehicles available on the Polish market, i.e. any camper with a serial chassis from Fiat, Ford, Mercedes, Citroen, Peugeot or Volkswagen can be retrofitted with suspension from this company. The exception are campers with a chassis modified by AL-KO.

If you would like to order exactly the same set that we have, you must ask for:

• 2 air springs with an installation kit designed for your vehicle
• Premium controller (with leather upholstery) 2DB - independent control of the right and left sides (controller mounted in the dashboard)
• 12V 200PSI X380 compressor with a set for external pumping

What is the cost of air suspension for a camper?

When it comes to MTT System solutions, a set of pillows with a compressor starts from PLN 1,900 gross. The same set that I installed at home costs PLN 2,500 gross.

The above price does not include installation, the price of which depends on the difficulty and technical condition of the car.
