Vanzilla is the nickname for the Loud family van.
The van has a green and white color scheme with two doors in the side, one of which has a broken lock and a window roller. It has four rows of seating; one with the drivers' seat and adjacent passenger seat and three with seats for other passengers. The license plate reads "LLLD", as seen on "A Tattler's Tale". On the front of the van is the word "FUNG", which may be the name of the van's manufacturer.
Despite the van bearing no resemblance to any other real life vehicle, the front grille resembles that of a 1964-1970 Dodge A100, and the headlights slightly resemble those of a 1961-1967 Ford Econoline.
