So, let’s dig in and find out the answer!

Answer for the Question

• While upgrading a regular cab truck with extended cab doors may seem like a good idea. The process is fairly complex and requires extensive modifications. 

• The doors themselves are different sizes, with extended cab doors being several inches longer. And taller in order to open up the expanded rear entryway. 

• The door frames are also in a different position on an extended cab. So the mounting holes and hinges will not line up properly on a regular cab. 

• Significant metal fabrication work would need to have a check to enlarge the rear openings and modify the wheel wells to accommodate the long doors.

• Additionally, the wiring harnesses, power lock mechanisms, interior trim panels, and rear seats are all designed specifically for each cab type from the factory. 

• Custom wiring and interior modifications would be ideal to make long doors functional in a regular cab. 

• Structural reinforcements may also be necessary to maintain the truck’s safety and integrity with enlarged rear door openings.

• While not impossible, fitting long cab doors to a regular cab is highly labour-intensive. 

• All of the required modifications may also mean it will be very expensive as well. 

• Depending on the truck’s age and condition, upgrading to a long cab model is more cost-effective than modifying a regular cab if extra space is in need. 

• Remember that the complexity, safety risks, and warranty impacts make this customization very challenging for the average truck owners. 

• Consulting an experienced mechanic or body shop is highly recommended before undertaking this type of project. 

• With sufficient expertise and effort, extended doors could potentially be adapted to a regular cab, but the benefits may not outweigh the substantial downsides for most pickup owners.
