It was I that asked the original question, now I can answer it myself. I am leaving New Zealand in the morning after having spent the last 15 nights in a motor home driving through both the north & South Island. I have owned motor homes for 30 years, this was the most incredible experience I have ever had.
The secenery was unbelievable, the RV parks first rate & they actually encourage what they call freedom camping, boon docking in the US
We rented from Wilderness New Zealand they worked with us closely and took care of everything but the food
Thanks for all the suggestions
Ps driving on the other side of the road is really no big deal do not let that stop you
