Bowler is a market leader in the production of racing and high performance all terrain vehicles, and has been since 1985. The UK pioneers in Rally Raid cars, Bowler have designed, developed and produced some of the most innovative, durable and exciting all terrain vehicles ever seen. Bowler use both technology and craftsmanship to deliver vehicles with style, strength, performance and an unrivalled spirit of adventure.”

It was no surprise then that a Kimberley customer passionate about Bowler products sourced original Bowler wheels for his new off-road camper trailer by Kimberley.

We have seen a lot of wheels at Kimberley but nothing with the strength and quality of these.

Designed and manufactured in the UK, these lightweight high strength 18 x 8 inch wheels are exclusive to Bowler and are a direct fitment to Defender hubs for matching wheels and tyres between the Land Rover Defender and the Kimberley Platinum camper trailer. Available in white, anthracite and black, they are available from Bowler in the UK at £325 each.

What else did the Kimberley customer order?

On the Kitchen side:

Master Galley Kitchen for off road camper trailer

The standard Platinum features of Stainless steel Master Kitchen that pulls out on roller bearings with one hand; the stainless steel dining bench, concealed underneath means one less table to carry; the BBQ and large WOK burner; the clever split pantry that also glides with one hand; and off course the diesel hot water system plumbed right to the sink at the end of the kitchen slide.

Flipping down inside the Gullwing lid is a 22 inch TV that will show DVD’s and TV as you require plus the Smart touch energy, water tank and switching system…. Read and control all of the systems in your camper just like using a smart phone!

In the front Gullwing area of the off-road camper trailer:

A high capacity fuel cell; a 10L methanol cartridge, a Digital DVD, FM, AM and MP3 player, a high gain modem/router for the bush with a 6db antennae. Missing are the 2 x 20L Jerry cans. The Fuel cell automatic controller is shown on the back wall.

On the drivers side Gullwing:

A Weber Baby Q, the diesel hot water system with visi-flow lift of 4m from a billabong or stream that bypasses the tank; the compressor of a 2.2kW split air conditioner; the 3.5L diesel tank (good for at least a month) and then look at the detail on the air suspension system:

Passenger and Driver side paddle vales so that you can get the Kamper perfectly level when at a campsite; below these is the airbag pressure and temperature monitors that display the readings on the in-dash display. This is patented by Kimberley.

The performance features of this off-road camper trailer are that it can travel at better speed over difficult conditions, thanks to the air-suspension and superior assisted disc braking.

For a similar specification, Kimberley is 200kgs lighter than any other in its class. It is hard to beat this low weight distribution.

In-car monitoring of air-suspension pressure for off road caravans

TPMS with Airbag monitoring offroad caravan resized 600Now you can monitor your Kimberley Air Suspension with the same TPMS that monitors the tyre pressures on your vehicle and off road caravan or camper trailer. It can trigger an alarm on pressure loss or temperature variations. To improve safety and driver confidence Kimberley have introduced continous monitoring of the air suspension pressure and temperature. It is so innovative, it is patented.

Suspension innovation is probably the most important factor in a 4WD’s off-road superiority.

In 1970, at a time when almost all 4WDs used primitive leaf springs, Range Rover pioneered the use of soft, long travel coil springs on all four wheels. The benefit of extreme axle articulation became clear to everyone.

Then in 1993, Range Rover suspension design took another leap ahead into the next generation of innovation: electronically controlled, self leveling, variable height pneumatic suspension. (This is where we are today with off-road caravan air-suspension, some 20 years later)

This gave the driver the ability to reduce ride height for high speed cruising, increase it for off-road clearance, maintain a level ride regardless of load, and maintain articulation. The staggering capabilities of this system, in combination with the simultaneously introduced electronic traction control, took the 4WD world by surprise.

Air-suspension has significant benefits with off road caravans and camper trailers.

Reliability.

When air-springs (air-bags) were first introduced, the air-bags were rated at a maximum pressure and loads were pushed past this. In addition, the mechanical fixing of the air-bags, the fittings and compressor were not always as reliable for the high duty rate.

Overall, the market accepted the innovation but reliability stories held back overwhelming acceptance.

Reliability is now up to par with mechanical systems. Prices are now reasonable especially replacement air-bags which can be sourced in many locations around Australia.

However, there is one major concern to air-suspension. The unlikely slow leak!

Just like a tyre, a slow leaking air bag could rupture on an agressive corner. The sudden loss of pressure and potential swaying could severly unsettle the driver let alone lead to lead to an accident.

To improve safety and driver confidence Kimberley have introduced continous monitoring of the air suspension pressure and temperature. It is so innovative, it is patented.

The system uses the Kimberley TPMS. You may be able to use an alternative TPMS systems but Kimberley have tested and proved it with their own system.

The result is:

  • continous read out in your vehicle of the pressure and temperature in the air-bags on either side.
  • user set alarm points for drop of pressure and or rise of temperature
  • Wireless connected from the Karavan or Kamper Trailer to the vehicle
  • uses 2 slot positions on the screen for the air-suspension.
    There is a maximum of 12 positions so when 2 are used for air-suspension moniroring, this leaves 10 positions for the vehicle and trailer tyres.

In tandem configurations, 2 air-bags are coupled together and the system therefore monitors one side of 2 air bags rather than individual bags.

When used with the tandem “Digital control of Auto-ride height”, the system will monitor only 2 of the 4 air-bags. 

The TPMS system can be plugged into the 12V cigarette lighter source at the dash with the “repeater” plugged into a separate 12V source in the rear of the vehicle. These 2 items are connected wirelessly. The tyre and air-bag sensors communicate wirelessly with the “repeater” which in turn passes the signals to the colour screen.

The Kimberley TPMS Kit is sized for up to 12 sensors in total:

Pricing as of April 25th 2014 (subject to change):

TPMS System including colour screen, repeater and 12 Sensors – $1200 (excludes installation and air-suspension housing)

Air-suspension Housing for monitoring of 2 ar-bags (single axle or only 2 with Tandem axle): $490 (includes installation when ordered with new Kamper, Karavan or Kruiser but excludes TPMS) $390 without installation for housings only but no sensors.

The use of a TPMS system and housing for monitoring air-suspension pressure and/or temperature on Vehciles, Camper trailers and off road caravans is protected by an Australian Pending Patent. All images, information and descriptions are copyright of Kimberley Kampers Pty Ltd.

 

Suspension Design for Off Road Caravans and Camper Trailers

Guide to Suspension Design off road caravan and camper trailer Traveling off-road to out-of-the-way places requires long distances on both highways and off-road tracks.

You have a good choice of coil or air suspension with independent trailing arms.

However, if your caravan has air-suspension, you can drive faster and more confidently on typical rough roads or corrugations, where higher sprung caravans may be reduced to a kangaroo-hopping crawl.

Is the air suspension worth it? Read this eBook to decide.

  • 1. Independent Suspension Innovation in 4WDs since 1970’s
  • 2. Reliability
  • 3. Digital Age adds to Stability as well as Reliability
  • 4. The Difference with Caravans and Trailers.
  • 5. Camper Trailers and Caravans pre-2000
