What Are the Different Types of Truck Cabs?
The truck cab is where the driver and any passengers sit. The standard set of truck cab options include standard or regular, extended, double, crew, and mega cabs.
Standard or Regular Cab
Standard or regular truck cabs offer the traditional pickup truck look. Trucks with standard cabs have two doors and one row of seats, making this the smallest cab option. Regular cabs are the only ones you can combine with a long bed, so they are most often used for work trucks. Some popular models that offer a standard cab configuration include:
- Chevrolet Silverado
- GMC Sierra
- Ford F-150
Extended Cab
Extended cabs have four doors, but the back doors open backward, and this is the standard configuration for most modern trucks. The rear doors on an extended cab can only open when the adjacent front door is opened. Extended cabs have a small seat or extra space behind the front row, but not a lot of comfortable sitting room for any passengers in the back. Truck models available with an extended cab include:
- Chevrolet Colorado
- GMC Canyon
- Nissan Frontier King Cab
- Toyota Tacoma Access Cab
- Ford Ranger SuperCab
- Ford F-150
- Nisan Titan King Cab
- Ram 1500
- Toyota Tundra
Double Cab
Double cab trucks have 4 doors that all open conventionally. Still, the rear doors are smaller than the front doors, and the rear seating space is still tight (though slightly bigger than space in an extended cab). 
Children and shorter adults may fit comfortably in the back row, but most adults would not ride comfortably in a double cab back seat. This is still a popular cab configuration, as it does provide decent interior room in a reasonably-sized truck. A range of bed lengths is possible with the double cab. Pickup trucks with a double cab option include:
- Chevrolet Silverado 1500
- Toyota Tacoma
- Ford Ranger
- Toyota Tundra
Crew Cab
Like the double cab, the crew cab has 4 regularly-opening doors and two-row seating. The main difference is that crew cab trucks have more interior room. The seats are larger and there is more legroom in crew cab trucks, making them ideal for transporting people and hauling goods. Adults can comfortably ride in the back row of seats, and the seats can usually fold up for more storage. Crew cabs cannot accommodate a short bed, but they can be used with a regular or long bed. Crew cab trucks are incredibly popular for use as passenger vehicles, and some models include:
- Ford Ranger
- Chevrolet Colorado
- GMC Canyon
- Nissan Frontier
- Toyota Tacoma Double Cab
- Ford F-150 SuperCrew
- Nissan Titan
- Ram 1500
- Toyota Tundra CrewMax
Mega Cab
Mega cabs are also 4 doors and extend the cab by nearly a foot. They offer increased storage space, reclining seats, and a ton of leg-room. Typically, mega cabs are only available for heavy-duty trucks, and they come with a significant price increase. You'll only be able to get a mega cab truck with a long truck bed.
The Ram Heavy Duty 2500 and 3500 trucks are popular mega cab choices.
What Are the Different Types of Truck Beds?
The truck bed is where the cargo goes, and it's used to carry heavy objects. The standard set of truck bed options include short, standard, and long or extended.
Short Bed
The short pickup bed is about 5'8" long, but it depends on the specific model and manufacturer. Short beds are a bit unconventional and are only possible with certain cab configurations. However, they keep the truck compact, making it easier to maneuver and park, and they still offer some hauling space for yard waste, small furniture, etc. Short truck beds are ideal for those who only have minimal hauling needs and are looking for a smaller overall truck.
Some pickup trucks that come in the short bed configuration include:
- Chevrolet Colorado
- Ford Ranger
- Toyota Tacoma
- Ford Ranger
- GMC Canyon
Standard Bed
Standard truck beds are around 6'5", again varying based on the manufacturer and specific model. The standard bed is a common choice as it provides more hauling power than a small bed but is not as cumbersome as an extended bed. For most hauling needs, the standard bed will be plenty. It offers more room than the short bed but is still small enough for most garages and parking spots.
Long or Extended Bed
Extended or long truck beds are around 8' long, nearly two feet longer than the standard bed. Long bed trucks can carry the most weight, making them a common choice for commercial vehicles. Additionally, extended truck beds are often used to haul trailers. If you have to haul long lumber or other large items, a long bed truck may be the right fit. Keep in mind that you cannot get a long bed with all cab sizes.
- RAM 2500
- RAM 3500
- Chevrolet Silverado 1500
- Ford F-150 XL
How to Choose the Right Cab Size
Here are the most important factors to keep in mind when choosing a cab size:
- Truck Passengers. Will you commonly have passengers, especially more than one? If you have a big family or plan to use your truck to carry passengers, choose a cab size that provides enough legroom.
- Bed Length. Only certain cab configurations can support certain bed lengths. If you know you need a certain bed length to haul, then you'll need to choose a cab configuration that can go with it.
- Driving Distance. Are you using your truck for jobs around your area, or do you plan to take it on road trips? If you drive many miles in your truck, you want to make sure it's a fuel-efficient size and can accommodate passengers for long trips.
- Test Drive. Try out the different cab configurations in person to be sure you feel comfortable driving it.
How to Choose the Right Bed Length
There are pros and cons for each truck bed length. To choose the right bed length, consider:
- How You Use Your Truck. Is it primarily for work purposes, or do you use it as a passenger vehicle? You may not need an extended, or even standard, truck bed if you don't haul too often.
- Where You Drive. Long truck beds are very common on construction sites and farms, but they can be hard to maneuver through city streets and tight parking lots.
- What You Haul. Even small truck beds have hauling power, so you can use them to move many basic items. However, if you'll be transporting huge equipment or long items, consider a longer truck bed.
- Cab Size. Based on your truck usage, you'll have to pick a cab size that accommodates your passengers. Not all truck bed sizes are suitable for all cab configurations, so the type of cab you choose will impact the truck bed you can pick.
