question about drawer slides

Hello everybody.
The Command Post as I'm building it does not have any counter space inside. My wife opted to trade counter space for more storage space. I thought we might need counter space inside. As a compromise I decided to make a slide-out work surface. It seems simple enough, A nice hardwood table top that slides out on a set of heavy duty drawer slides would be perfect.
I drive a tractor trailer for a living, and my truck has a slide out desk top that is very similar to what I want. One feature the truck's slide out desk has is drawer slides that lock in the extended position to make the desktop more stable. I want those same sort of locking drawer slides for the camper, but I'm having no luck at all finding them.
Maybe I don't know the proper name for the things to search for the correct words. Anyone have any ideas on how to find what I'm looking for?
thanks
