ReAX, I believe it is only '01 and earlier models where the keyless entry will not work with the engine running. 02 and newer it's not an issue.
I believe the GEM is what controls the keyless entry, and don't think you'd be able to do the same kind of wiring like in that link on our trucks to get it to work.
A remote start system would however override that and allow you to lock/unlock the truck with it running, or even remove the key while the truck is still running.
