When two of my daughters and I hired a motorhome to travel around the South Island of NZ, we chose a 6 person one. It had heaps of space and I drove it easily. I'm used to driving on the LHS of the road ( I'm from Australia). It had everything! A full-size fridge. We did a big grocery shop when we collected it and didn't need to shop again apart from wine at local wineries. A would never hire a van that I couldn't stand up in. That would not be fun for me at all. Neither would I hire one where the dining table converted into a bed. These are just my personal experiences. We travelled in July so got a super cheap deal.
