Thank you everyone for your worthwhile feedback.
My journey has taken yet another dramatic turn as the family is now looking at investing in a caravan, Expanda to be precise. After some research and reviews it appears the Expanda is not what it seems as I have read comlaints relating to bad workmanship, leaks, screws falling out etc. We are looking for an easy set up and some good storage space, would love the Expanda as it sleeps 4 with loads of room. If you have or have had an Expanda I would love to hear your thoughts. My plans are mainly CP with the occasional dirt road, help.
