Berkley's RC van
A comparison of the back of the Pony (left) with the Berkley RC Van (right).
Berkley's RC Van is a variant of the Pony featured in Grand Theft Auto: San Andreas. The van is extremely rare and can only be seen sporadically driving around Bone County or near Las Venturas Airport. It sometimes has boxes of model cars in the back - the same ones that can be seen in Zero RC. Even though it's based on the Pony there are a few differences, like the taillight design and the location of the gas cap door. There is an optional side-mission called Beefy Baron in the back room of Zero RC in which you must destroy these vans with an RC Baron within a time limit.
Trivia
The vehicle's ID, model, texture, and text entry names are Topfun. Only the text string has the name Berkleys RC Van.
