I'd been toying with an idea to store all four doors up and out of the way somehow in my garage, since I lacked space for a rolling cart and never liked leaving them on the floor (on a sleep mat), easily accessible to my 2.5-yr old's hands.
I'd used the Rubbermaid FastTrack system around the garage, and decided to go with it again for the doors, using a single 48" rail ($10) and 4 ladder hooks ($10/ea) at Lowes. The rail is rated to 1500 lbs, but the weak links are the hooks, only rated at 50 lbs each.
I estimated 2 doors to weigh around 100lbs or slightly less, but with everything on, I was able to put more weight on the system and everything felt quite strong. The rail is secured to 3 studs, 2 screws each. I also added the typical foam insulation to keep the hooks from digging into door window gaskets.
