4 bunk caravan?

That would make a huge van. im thinking you may have to get one built to your requirements. We have a basestation 6 berth. Expanders cater for large families too thats if you dont mind the fold out beds.

Our Jayco Expanda will sleep 2 adults and 4 kids, 2 in bunks, 2 in front double bed. Our model is the 16.49.2, but no shower or toilet in our model. There are other expanda models that are 6 berth and include a internal shower and toilet.

thanks for all the responses guys.

the expanda and base station definitely look like the go.
