Can you post an example of a "real" bed extender? I've never seen one that wasn't the curved tube steel type sold with the RL. Are you talking about more of a slide out bed load floor like they sell for loading ATVs and golf carts?
There are also the hitch mounted supports which you can use for long material and those should work the same in a RL as in any vehicle with a hitch receiver.
