Welcome indeed!
Similar to yourself we collected our 6.1 this July. Our kids are 6 & 8. During October half-term we went down to Cornwall. We took our Vango Faros drive away awning. Well it was very windy most of the week but otherwise dry. After the first night it was still blowing hard and it was obvious that if we left the drive away awning up, whilst we went out for the day, it would not be there when we got back. We packed up the drive away awning. Me and the Mrs were concerned how we were going to get through the rest of the week in such a small space with 2 fairly energetic kids! It was an utterly brilliant 5 days, one of those you will always remember. I think the drive awning will be sold, such a faff. What is the point in having a drive awning if it cannot stand up in rubbish weather?
So yes, less is definitely more. Everyone has different ways of operating and we are starting to refine what we need to store where.
The major plus of the Cali is that we also use it to a day out more fun. We will go to a National Trust site, and after we have been for our walk get back to the van and have hot chocolates. Similarly we will take the kids to the beach (West Wittering) for the day during the winter and just being able to hide in the van for lunch/snacks/tea will be brilliant.
