Cabs
- Regular Cab — two doors. (Called the "Sweptline" regular cab on some 1990s trucks.)
- Quad Cab — extended cab. Since 2002 its rear doors are front-hinged and open on their own; before that it was the "Club Cab."
- Crew Cab — four full doors.
- Mega Cab — heavy-duty (and some older 1500) crew cab stretched for more rear legroom; always paired with the 6'4" box.
Beds
Ram names beds by length: 5'7", 6'4" and 8'. The optional RamBox adds lockable bins in the bed walls, which narrows the inside of the bed — RamBox trucks need RamBox-specific shells and covers.
Which bed is on which truck
- Ram 1500, 2019–today (DT): Crew Cab 5'7" or 6'4"; Quad Cab 6'4". Ram 1500
- Ram 1500 Classic, 2019–2024: the previous truck, sold alongside the new one. It uses the older 2009–2018 bed — a DT shell will not fit a Classic.

Why "Dodge Ram" became "Ram"
Ram trucks were sold as Dodge Ram until 2010, when Ram became its own brand. Trucks from 2011 onward are simply Ram 1500, 2500 and 3500.
