I like a "toolbox" type storage for the bed, for things bigger than I want to put in the cab and just leave in the Ranger. Gloves, hammer, pruners, zip ties, etc. I can keep things dry in the rain, and locked away from critters.
The storage box for Polaris Ranger is an excellent accessory for long rides, weekend trail excursions, and work-related duties on the farm, homestead, or construction site.

Our Rangers live in a barn with no electricity. I added a rearview mirror with LED light on it. It helps getting in and out when it's dark out. A backup light is handy for the same scenarios.
