Best way to secure a 2-door dorm-style fridge?

I'm thinking of putting a 2-door dorm style fridge in a new Freightliner Cascadia Evolution (company truck.) I'd like to get it off the floor and out of the way. I'm thinking about methods of securing it. Of course, the company doesn't want any drilling of holes in the truck. One thought is setting it on the (mostly unused) upper bunk, attaching a plywood base to the leveling leg sockets, and running ratchet straps through that and around the upper bunk. Any other thoughts on methods of securing this? I'm also at a bit of a loss for what I'd do to secure it if it was on the foot of the lower bunk. Any thoughts anybody?

Here's a link to the general type of fridge I'm thinking of:

Gee, perhaps that is why this thread is titled

Any other insight?

 

I was thinking of perhaps "platforming" it to plywood, using the leveling leg sockets as anchors. And setting that on some memory foam to dampen the shock. But I'm having trouble picturing what you described here. I not only need to secure the fridge in a place that has few anchor points in the cab, but also need to do it in a way that does not restrict opening the fridge/freezer doors. And certainly don't want to drill the fridge case to mount any anchor points either.

Also, any reason for preference of bungee cords over ratchet straps?

Do you by chance have any photos?

 

So the bungees were going around the fridge (including doors), and had to be unhooked each time you went into the fridge?
