In-depth look at each cab size
Regular Cab
The Regular Cab is Ram's two-door configuration, prioritizing payload efficiency and affordability. It has limited rear seating and is best suited for work fleets and users who don’t need rear passenger space.
Quad Cab
The Quad Cab adds four doors and smaller rear doors, expanding access to the back seat while maintaining a compact overall footprint. It typically pairs with shorter bed options and serves families or groups needing extra seating without the size of a Crew Cab.
Crew Cab
The Crew Cab is the largest passenger-oriented option, featuring four full-size doors and generous rear legroom. It’s the default choice for families and crews needing maximum interior space, with various bed length options to suit hauling needs.
Mega Cab
The Mega Cab is a larger extended cab with extra interior space and unique rear doors. It was available on certain Ram models in the mid-2000s to early 2010s and has since been discontinued; contemporary Ram lines no longer offer this configuration.
Choosing the right cab for your needs
When selecting a Ram truck, buyers should consider how many passengers will ride regularly, how often gear will be transported in the back, and the preferred bed length. Because cab availability shifts by model year, it’s essential to review the exact specifications for the year and trim you’re considering.
Summary
Ram cab sizes center on Regular Cab, Quad Cab and Crew Cab, with Mega Cab appearing on older models. The Regular Cab emphasizes efficiency, the Quad Cab balances access and space, and the Crew Cab maximizes rear-seat room for families or crews. For most modern Ram pickups, Crew Cab is the common choice for passenger comfort, while Regular and Quad Cabs remain available for certain trims. Always verify the cab type and bed length for the specific model year you have in mind.
