I have a wife, two kids, a dog and a stupid cat. Bugging out during a hurricane would tax the interior space of the Discovery as it is. I don't think keeping them inside will really work for me. I do appreciate the ease of that solution, however.

 

Here is an option for a rear mount, SmittyBilt iRack 2:








P/S. I am in not any way related to Mr Bezos, Mr Smitty or Mr Bilt

 

I have mine set up on my rear-tire (bumper mounted) swing away. It takes weight off the cargo door.

Before I had my rear tire swing away, I mounted the iRack on the spare tire carrier which was directed mounted to the cargo door. I was able to carry a Spectre 5-gal fuel can. Caveat is it does place additional weight on the cargo door.

 

I find the idea of the rear tyre swing away mount interesting. how much easier is it to open and close the rear door? What did you use for the mount?
