I did see a film of flat-jacks which could be stacked on each other. Is this possible?

Answer: yes, that is possible. There are two kinds of flat-jacks for campers and caravans. The one we sell is the flat-jack Camper Plus which reaches 12 cms of height. The other one is the smaller flat-jack Camper, which reaches only 6 cms of height. This flat-jack Camper version can be stacked, but maximum to be stacked is 2 pieces, which leads to the same 12 cms height as 1 flat-jack Camper Plus. The price of 2 flat-jacks Camper is almost double the price of 1 flat-jack Caper Plus. That is why we only offer the flat-jack Camper Plus, being more efficient.

Answer: The instructions for use will be sent to you together with your invoice when you order your flat-jack through our webshop. If you do not have this e-mail with invoice and instructions for use anymore, you can send us a request through the contact form on the flat-jack website to receive again the instructions for use of the 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.
