Hello and Help!!

Hi,
My wife and I are hoping to sell up and travel through France and Spain next year. We are complete camper van novices and so would really appreciate some help and advice on getting going! We are aiming to buy a small[ish] van at the end of the year and would really like some advice on what type would be the best bet for 2 middle aged, non mechnanically trained, adventurers! This is a big life change for us and it would be great to hear from anyone that has followed the same.
Thanks for any advice or comments!
