The model that i have found for our trucks are the RF945US shallow drawer with roller top and RD945US is the deep drawer like [MENTION=46022]Jones[/MENTION]eeyyy has. The drawers with roller tops have locks on the drawers, but not the rollers so they are accessible. Without the roller top they lock. Ben has a thread that I attached the info that I was sent and posted. Thread is ARB Drawers I think.
Ben also did a write up DirtRoadTrip dot com on them and his opinion.
