So I said I'd add some details of our "full" pack, this is for our annual large roadtrip to Loch Tay and we travel 6 up (4 adults 2 younguns)
Hopefully this can give some inspiration for how to get a lot of stuff into a Caravelle. Coming from the massive capacity of a XC70 estate boot and a 450l top box I'm amazed how much we can actually get in. This is in addition to the "standing equipment" that lives in the van and kitchen pod - must do a post on that some time.
As for the shorter road trips noted above the first set of packing is in Really Useful Boxes. We can fit 3 lots of either a 36l or pair of 18l across the top of the kitchen pod. To do this I need to move the bench a couple of inches forward, but this opens up a useful slot to drop the luggage cover unit in to - with foam strips around it to stop damage and rattles:
Then we stack the boxes in, again wrapped over with dense foam strips to prevent rattle and damage. In this case a 36l with younguns toys and crafts, a 36l of tall food and bottles, an 18l with all our tech and another with more food items:
We then pack almost everything else in 32l barrel bags, the softer squishy ones go in around the boxes at the sides, this is also a good place for hiking boots:
You'll note we have the headrests up and a selection of flat bungee webbing straps. I now pack the remaining bags vertical and secure with those straps. You can tuck softer ones right around into the window voids, otherwise they fit 2 deep on top of the boxes. This trip we got 11 bags in but I could probably get 14 in:
Inside we use the big duffle bag from before to pack everyone's coat hats scarves etc. This goes between the younguns seats in the middle seat belt for the trip up and back, but during the week it lives on top of the kitchen pod and allows use to lift all that gear in and out of the van in one lift, handy to dry everything in the apartment's drying cupboard:
It's a 12 hour trip up so the "cabin" needs to support us during that time. So the kitchen pod coolbox actually gets used packed full of frozen food for the first couple of nights (when we don't want to cook) but it works so well with a couple of 1kg ice packs nothing much defrosts. We take our electric coolbox (not our fridge) in between seats with all the fresh food to picnic on the way up, it fits well between the bench and the table unit as we have the back arranged "railway" style not "airplane" style. We don't normally bother plugging it in as it's fine on ice packs for that time.
Finally we need a place for everyone's personal bags/backpacks and non cool food snacks. With the seating style there is a useful space between front and mid seats to stack bags and we got some rather nice VW Camper decorated medium hessian shopping type bags that let us organise things behind the table unit and between the front seats:
And that's how we get 6 people from one end of the country to the other in relative comfort and self sufficient apart from the occasional loo stop - we try and hit every Tebay group services from Gloucester to Cairn Lodge!
When we get there everything unloads very quickly and then during the stay I move the bench back to it's normal position and put the luggage cover back. The duffle bag gets all our outdoor gear in and out easily and we fill the kitchen pod coolbox with the day's picnic and icepacks frozen in the apartment.
