What to buy? Motorhome, Caravan, 5th Wheel or ANO

Hi all

Right now, what to buy is our number one question.  As we will be living in it fulltime with 2 children and a dog until we find another house or something, we are finding it difficult to find something that meets our needs :-(

So far the list of wants are as follows:-

1. Not too big for campsites

2. Will be accepted on Britstop sites or something similar if funds are short (which kind of rules out caravans)

3. Be roomy enough for us all.

4. Has enough storage

5. 6 berth minimum so we don't have to keep making up beds.

6. Be able to take 4 bikes

7. Be able to stop / divert on our way somewhere if we see something of interest.

8. Be easy enough to pack away as we may move every few days.  Or we may be stationery for a few weeks so can use an awning then.

9. Be cosy enough in the winter in case we haven't found somewhere by then

As I am sure you will all see, this is proving to be a dilemma.... 

To add to this, our house completes in 4 wks... yikes!! We have a tent though so can always camp if weather stays good enough :-)

Any help, guidance, advice will be very much welcomed from you all. 

For reference as a few people have asked me this, we have a pre 1997 licence (passed out tests late 80s).

Thank you all soooo much in advance.
