Hi Blue Heaven,
I have a similar issue with regional trip ranges that I am now contacting hotel/motels wineries etc on the presumption that most will have a 440V 3phase power requirement for their everyday operations. I carry a new portable 3 phase charger(care of Timpoo) ,means that even a short exposure will load 22Kw is very helpful. Most Caravan Parks have 10A/ some 15Amps available but needs an overnight stay in many cases depending on charge levels etc. In my case I cover huge Kms per day in runs -so pausing for charge is a major factor. As I get confirmed info for country Victoria and Tasmania I will share...:biggrin:
