We have just returned to Perth after East Coast trip, I should have added this recommendation earlier.
Due to operator error (me), I hadn't connected the Anderson plug correctly and when we got to our destination at Soldiers Point, NSW, I found the plug had been dragging on the floor and was ruined (luckily it hadn't arched out). Anyway, I phoned a number of repairers and local electricians, however, nobody could assist, we were heading to Tamworth, I googled local repairers there and found Capital Caravans, I phoned them and they said just call in on your way through and will help, I said I might be late Friday afternoon, no problem. We got there about 4pm, they immediately replaced the plug, cost $45 including parts (I had been quoted over $100 elsewhere), they provided excellent service at very reasonable price.
