"Of all the caravan movers on the market today, nothing grabbed my attention more so than the CamperTrolley-CT1500 by Kronings Aps of Denmark. This small, well engineered, self contained unit has the power to move anything up to 1700 kg at about 9 metres per minute – now that’s a nice controllable speed.
What convinced me most is that the CamperTrolley is portable and relatively light-weight (16 and a bit kilos). No problems with dirt or moisture on your travels unlike other permanently fixed units. It comes with a sturdy travel bag. It also fits to both 100×50 mm and 150x50mm box chassis without any welding or drilling for bolt holes. One quick-fit clamp system and you’re away."
