There are many names for pickup truck cab types. Regular Cab, Standard Cab, Access Cab, extended Cab, King Cab, Quad Cab, extended Cab, Super Cab, Super Crew, Crew Cab, Mega Cab and Crew Max to name a few. Each pickup truck manufacture tends to come up with their own name for a cab style. Over time, these names and definitions have evolved. When buying aftermarket pickup truck accessories, this can cause ordering issues. Here is a guide to help make ordering accessories for your pickup truck easier.Ultimately, there are 3 types of pickup truck cabs. Regular cabs, extended Cabs and Crew Cabs. Through vehicle evolution, the exact definition has changed.
Regular Cab: A regular cab has a single row of seats and a single set of doors, one on each side. A regular cab always used to be a pickup truck with 2 doors. However, with the 2008 Ford F250 Superduty, their regular cab now has 2 very small rear doors.
Extended Cab: The extended cab started out as a pickup truck with 2 doors that had extra space behind the front seats and 2 rear windows. Through evolution this cab style added rear seating and a 3rd door. Today the extended cab pickup truck has 2 front doors, rear seating and 2 rear doors that can be opened if the front door is opened first. Today, each pickup truck manufacturer has their own name for this style of cab.
