Hi read on here about people using ikea under bed storage boxes as carcass trays!
So thought i'd go and have a look (had meatballs & chips too)
It looks quite sturdy and hasn't got any holes in the bottom - could be a winner at £7.99
Even comes with a folding lid - you can use when its empty.
Have put a pic on of the box sat in the boot of my Audi A3 and it fills it!
