Driving around in a Motorhome

Driving around in a Motorhome

I plan to visit NZ southisland in the 2nd week of September this yr and drive around in a motorhome for 3 full days. What will be the weather n road conditions like then? Plan to visit Chch,greysmouth, fox glazier, milford sound, queenstown, mountcook. Is this too much to cover in 3 days considering the distance between places? How do u rate the transalpine journey from chch to greysmouth? I have also heard of the doubtful sound is this better place then milford sound?Thanks in advance

Question about Drive New Zealand's South Island

The South Island is basically temperate and September is the first month of Spring so on an average year it's going to be sunny and warm in the sun but breezy & around 16 -17 degrees max. Don't discount rain.
