Big Mark’s mate and fellow pawnbroker Rick Harrison flies in from Las Vegas for some R&R and quality sightseeing and Mark attempts to impress him with a trip to Caenarfon castle, but getting back home is another thing altogether. Then Big Mark and Little Mark go for a little test drive in a giant tank. But after Big Mark reaches for the sick bucket, will he have any fight left in him to do battle with an owner determined to make some serious money? Later Simon and Marco take a little roadtrip when they are offered the chance to buy a 1960s Dormobile Campervan. Will the odd couple take the opportunity to own this very British vehicle or let this campervan pass them by … in the slow lane.
