I think it would be a stretch to call Forest Service roads 551 and 556 "4WD trails;" they are well-maintained gravel roads. Some of the roads that branched off of them required high clearance, but these roads didn't.
I included the videos on this page because they didn't quite fit into any of the other categories.
