Storage of removed door in trailer

Looking for ideas for best wall mount storage of driver door removed while in trailer. I see some bracket kits but seem expensive for what they are. Any other hanger ideas? I would appreciate any pics.
Thanks

Man I wish I had pictures of the setup I had in my trailer for my Daytona door. The pins slid down in some collars and the door locked on a weld on door striker. A Moparts member has my Daytona but I’m not sure he uses that system. Hopefully he sees this.

Thanks for the reply. I am sure someone here has a good set up tp share.

Temporary (like at the track) or while traveling ?
The fold-down bike or tool brackets I've bought from Home Depot would work for that at the track; trailer-mounting would require some cleverness.

Mounting in the trailer while traveling is my goal. Some type of hanging brackets maybe?

I have always used the RJ kit on both gutted steel and glass doors. Never and issue with it but make sure you go into a stud for the latch..

one could always use some 1/4"x2" or 3" [or whatever width needed to weld on a spare set of hinge plates and latch mechanism] strap steel to span between studs if the door is shorter than the stud spacing would allow all parts of the door mounting mechanism to attach to.

Thanks for both ides. I did see the kit but I may look if I have extra hinges laying around, should be able to build something for less.
