I don't have access to any of our vans this weekend at the moment - if that changes I'll let you know.
You can borrow the Mondeo if it'll fit (may stick out the tailgate)
Pay load with the seats down is :
2000mm long (from where I have my seat positioned)
790mm High (minimum - 850mm average)
1140mm Wide (minimum)
There's cargo tie-down points in the back so securing is simples.
