At lowering the flat-jack, I turned the valve cap completely off the valve instead of partly. Now my flat-jack cannot be stored completely flat anymore. Is this a guarantee case?

Answer: when the valve cap is completely turned loose from the valve, it may happen that the flat-jack, under the force of the recreational vehicle, is lowered too fast. This means that all the air in the flat-jack is forced out of the little valve with extreme pressure. This may result in an extra alternative pressure on the inner partitions of the flat-jack. These partitions can then rest partly upright instead of move completely down when the flat-jack is lowered. Your flat-jack keeps on functioning without a problem and inflating is just like always, but storing your flat-jack completely flat is not possible. The motto is: Just follow the instructions for use and let the flat-jack lower gradually. Do not take the valve cap completely off the flat-jack at lowering procedure, but only unscrew the valve cap partially to let the air flow out of the flat-jack gradually. Just like you do when you lower [...]

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: Always take care that your camper/caravan/folding caravan is exactly in the middle of your flat-jack. Both in length and in width in the middle. If this is not the case, the load of your vehicle (thousands of kgs) is all focused on one side and can make the weld seam break. This is not a guarantee case, because the instructions for use are clear: put your vehicle exactly in the middle of the flat-jack, so each weld seam (front and back side, right and left side) of your flat-jack is burdened equally by the load. If you have an exploded weld seam, this indicates you either pumped the flat-jack with pressure over the maximum of 1.2 bar or you were not centered in the middle on the flat-jack, so one weld seam was more burdened than the other.

We regret that this has happened to you. That is why we, as flat-jack importer, will [...]

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.
