Access cap long bed or double cab for off road

I'm looking for help to figure out if a access cap long bed would be better then a double cab short bed for a off road build with a project M in the back, (there's a access cap long bed in my area for a good price with a lift kit, flood lights and grill protector) also don't got a big budget for a build.

 

They are the same wheelbase. What cab/bed configuration meets your needs/wants better?

 

If you do not need the rear seating space, 100% go with the longer bed option.

The extra bed space will be useful for camping. Every inch counts in these tiny beds.

 

What are you transporting primarily- people or gear?

 

Primarily climbing gear with one extra person.

 

Project M is this monstrosity? Go for the access cab because the base vehicle is lighter and leaner.

 

Yeah if you’re trying to put one of those things that @3JOH22A posted above on the truck, definitely go for a long bed.

 

Any access cab is fine.
Not sure what you would need all the extra seats of a DC for.
