Vanzilla is the nickname for the Loud family van.
The van has a two-tone 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 distinct resemblance to any other real life vehicle, it takes design cues from various vans of the 1960's. The front end of the body appears similar to the 1964 ChevyVan. The front grille resembles that of a 1964-1970 Dodge A-100, and the headlights slightly resemble those of a 1961-1967 Ford Econoline. The rear profile of the van also appears to be taken from the Econoline. It also has the split-screen windshield and taillight placement of the 1950-1967 Volkswagen Type 2. However, it also has some traits of more modern minivans, giving the van a more anachronistic appearance. The windows on the van are much larger, less round, and has less windows than 1960's vans. It also has single rear doors on both sides that are hinged, similar to the 1994-1998 Honda Odyssey.
