Maybe if it didn't say PackRat on it in huge lettering - if it looked stock... as Toledo FJ said, the security issue kills it for all but on the trail use, e.g. stuff it in the morning, unpack at night.
If you're looking for stealthy places to keep recovery type stuff, look in the rear compartments - pull the panel on the left: lots of room there. Pull the tray on the passenger side - there's a great "hiding" place under it. I have jumper cables, first aid kit, winch remote and a small tow strap all hidden in the cargo area.
