Do I always have to drive on a flat flat-jack and at the end of the holidays drive away from a flat flat-jack, or can I also drive on a full flat-jack?

Answer: Never mount or dismount from a full flat-jack. If you do so you can damage your flat-jack. This is not covered by the guarantee. Only drive on and off a flat flat-jack!

Answer: on normal campings you can use a simple ultra lightweight foam mat (the ones you use for doing your garden work on your knees), or a floor mat. In cases you are outside the campings and more adventurous, like in the mountains, in the fjords in Norway, in the forest, etc. we advise to use a protective mat which is more thick, like a carpet tile or even a classic coconut mat (without holes) or a wooden or metal plate under the flat-jack for extra protection against tree roots in the forest, stones, rocks, etc. Always first remove any big stones, etc. before you put up your recreational vehicle and use your experienced camper brains to decide whether the place is suitable for using your flat-jack.

Answer: the ramps for leveling recreational vehicles are indeed on the market for more than even 50 years. The flat-jack is the first modern alternative which has many advantages:

  1. Biggest advantage of the flat-jack: not driving on a slope of the ramp, but driving on a simple flat cushion of the flat-jack, so far more easy to mount.
  2. Second advantage of the flat-jack: level much more detailed, even on the millimeter, because the flat-jack operates with air, which is stepless. You can be perfectly horizontal.
  3. Third advantage: you drive on the flat flat-jack, inflate the flat-jack, and ready. You never have to relocate the flat-jack anymore, like with the ramps. With a flat-jack you are directly on the right spot. You only have to pump for reaching the right height and that’s it.
  4. Fourth advantage: the flat-jack has a big surface, so she does not sink in the mud like ramps. Digging out the [...]

Answer: no, you can not stack more flat-jacks Camper Plus. But if you want to be higher than 12 cms, you can put a big 3 or 5 cms high platform (wooden or metal) under your flat-jack before you drive on the flat-jack. In this way you keep your vehicle stability on the flat-jack and still create extra height. And doing so, you can overcome still higher slopes on the camping.

Answer: a mini-compressor is more comfortable, because she takes less energy which is good, the more so in warm holiday/summer weather, but a compressor is more risky than a bike pump. During the pumping process with a mini-compressor, the pumping person can be distracted by a mobile phone for example. During the telephone call the compressor just keeps on pumping, and people can forget the compressor, which then over-inflates the flat-jack in the end. This can result in an exploding flat-jack, if the mini-compressor pumps her up above 1.2 bar.

Answer: in the flat-jack you will find an IN valve. This is exactly the same valve like in your car wheel, so the flat-jack has a universal valve. With any bike pump, foot pump or mini-compressor you can inflate your flat-jack on this universal IN valve. Attention: almost all modern bike pumps have a double adapter. One side for bike tyre pumping and the other side for car tyre pumping. The flat-jack is inflated with the car tyre pumping side of your bike pump.

Answer: always remove big stones and rocks before you put the flat-jack in place.

Answer: yes, you can stand with your flat-jack directly on small river stones and gravel campings. The flat-jack material is polyurethane, which is resistant to small river stones and gravel. Even with a heavy camper of 7500 kgs you can use the flat-jacks on these gravel campings. But we always advise our clients to prevent the flat-jack from a leak caused by too sharp stones, by putting a protective mat (floor mat or carpet tile) under the flat-jack. Between the stones there could be a piece of glass or a tent herring, so it is always wise to protect your flat-jack.

Answer: no, even children of 6 or 7 years old can pump up a heavy 7500 kgs camper, because the flat-jack only needs 1.2 bar (17 psi) of pressure since the flat-jack has a big surface which lifts the camper easily at little pressure. With a simple bike pump you pump up a normale bike’s tyre at 4 to 5 bar pressure, so pumping up a flat-jack with only 1.2 bar of pressure is far more light and easy as pumping up a bike’s tyre. Ideal.

Answer: only 1.2 bar (17 psi) of pressure is needed for the flat-jack to pump her up to the maximum height of 12 cms. This is a quarter of the pressure that is needed for a simple bicycle (which needs 4 to 5 bar of pressure). This is because the flat-jack cushion has a big surface, which makes that only little pressure is needed to lift big weight vehicles like a camper on this big cushion. That is the lovely property of air. With a lot of square cms (like the flat-jack) air lifts gigantic weights of vehicles easily.
