I have 2 electrical panels separated by about 12-14", located outside with NEMA 3 panel boards. I am using 2" rigid conduit between them. Do I need connectors on each end of the rigid conduit, or can I simply put a locknut and a bushing and each end.
 
You need two locknuts, one outside and one inside where the conduit goes through the hole of each enclosure. The bushing goes after that. That's the way I do it.

Depends on where the live parts are in relation to the RMC.

312.2 Damp and Wet Locations. In damp or wet locations, surface-type enclosures within the scope of this article shall be placed or equipped so as to prevent moisture or water from entering and accumulating within the cabinet or cutout box, and shall be mounted so there is at least 6-mm (1∕4-in.) airspace between the enclosure and the wall or other supporting surface. Enclosures installed in wet locations shall be weatherproof. For enclosures in wet locations, raceways or cables entering above the level of uninsulated live parts shall use fittings listed for wet locations.
Exception: Nonmetallic enclosures shall be permitted to be installed without the airspace on a concrete, masonry, tile, or similar surface.

Agreed. Otherwise, the conduit is not secured.
