I read the MUD Post. I was already going to recommend that I err on the side of caution and advise against 7 Mile for you. It is hard for me to recall all the tough spots after driving it in a lifted, locked and armored 80,
but I suspect you would drag the tail and have to be super careful about the rockers.
Other fun drives include the Dubinky Sand Dunes, Gemini Bridges, back road into Arches, and one of the "bottom" roads to the River.
Any of the easy rated trails in the Charles Wells book would be fine. Chicken corners will be fine (and fun and scenic - I'm leading it Friday and just pre-ran it). I have explored a lot around Moab and happy to share what I know.
