A large collapsible gear tub that folds flat when empty.

The container for everything you do not want loose in the vehicle: muddy boots, wet waders, a dripping tent, sandy kit after a beach day.

Also the big wash basin when the sink is not enough, and a soaking tub for a pan that needs overnight.

Folds flat for the drive home, which is the difference between carrying one and not.

The item that keeps the inside of a truck liveable on a long trip.
