I've seen that trailer before, on here I think, I'll search for it. Its the best sandman one I've seen done. I have thought about doing similar but have been concerned about tow ball weight using the van as opposed to a ute. Using the van the front is the firewall, but a ute could start at the front of the tray, ute would be better balanced. Did anyone talk to the owner? That said the van would have a great amount of storage.
