I dont get why you wheel it in and out daz, is there no access to pull up to where it is ? so you pull it out and put it near your van to fill ? how long does it take to fill ?
Seems a bit of a pita, surely if you cant have a static it would be easier just to have to RO onboard and just use van ports up to a tap ?
I basically wheel it a couple of yards to just under the kitchen window (where the outside tap and drain is) and position it right behind the van for fill up. It works perfectly fine and no hassle at all.
