Might need to replace our old T4 Caravelle soon. It only gets used with 5 seats in it, with the boot for bikes/camping gear etc. How much smaller (if at all) is the load space in something like a Galaxy with the same seat configuration? As a guide we tend to pretty much fill the rear up to the window line when heading off for summer hols, and that’s with the bikes on a rack on the tailgate. Any practical experience of using both would be greatly appreciated.

What about using a roof box?
