I am the proud owner of a not too large motorhome. For the filling of the fresh water tanks you need a water connection and a hose with the appropriate adapters, if you do not want to haul 100 liters by WaterCan. As the storage space for the many things that you "absolutely" needs, with a rather smaller RV always is tight and the hose should have a certain length already, because the taps are sometimes a bit away from the mobile home and you also unspecified can drive up and the hose then in standard design has a very large footprint, this version to me came in handy as a flat hose. The storage is not much higher than the flattened tube is wide and the width of the retention measures at any point more than 40cm. The triangular shape makes this a very space-saving storage at all times. The weight is here compared to a normal hose negligible, also an argument for campers. It is true that you have to roll the hose each time completely, if you want to use it, even when only two meters away faucet. It is likewise correct that the knob that serves as Aufrollkurbel very easily detached from the hose storage and thus the rolling can be annoying. It's a little trick: I'm considering container quasi horizontally on the forearm, so that the knob is pointing upwards and the operation when rolling the hose is similar to a hand-grinder. This one has the possibility to press the knob at the same time a little more toward the Aufrolltellers and he slips no longer quite so easily from its mounting. When rolling up the hose you must also make sure that it is as straight as possible (preferably a little downhill) or in large sheets. Definitely a kink may be nowhere, because otherwise the residual water in the tube can be pushed out of the tube does not run or which then makes a rolling impossible. Despite these undeniable disadvantages my smaller footprint to one tenth compared to a normal tube of the same length is important. Taking in a normal hose also a Aufrollteil added, which is barely accommodate reasonable in a 3.5t camper. The material of the flat tube is apparently very high, since even after more than two years of frequent use of the tube shows no cracks or other damage and leaks sometimes not. He is not treated particularly care of me and rolled up when it is wet outside and at any temperature. For me, this is a water hose and he has to deal both inside and out with water without suffering any harm that.
