Can I also stack more flat-jacks on each other if I want te be higher than 12 cms?
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.
