Anybody interested in product like this? www.doorcaddy.weebly.com I developed this myself and I am looking to market it. I got tired of leaving my doors or putting them in the back seat. If anyone is interested feel free to contact me.
I think it's a pretty cool idea. Would be useful when going on a road trip where you want to take the doors off but still want to bring them with you. Any theft protection for the doors while they are on there though?
What I have done in the past was to take a bike cable to lock a bike with and locked each end to the rack after putting it over top of the doors. This prevented the doors from being lifted up or opened.
