We are planning to visit Iceland in March next year (2015) from around the 17th to 22nd. We are a family of four (our kids are 10 and 7).
I read a bit on the weather and road conditions and I am unsure a campervan or motorhome would be ok to drive in the second half of March.
I am a very good driver, very experienced in winter driving and off road situations. I can say that I enjoy driving in harsh conditions. I also used to own a small motorhome so I know how they work and can judge the limitations.
