Tow Vehicle Feedback Appreciated

I'd invest in a good equalizer hitch, load light and drive conservatively. The Hemi is a beast and if your rear end is right - you'll be good-to-go. I think that RV'ers of all types will usually be better served to do good pre and post-trip inspections and use safe driving principles and techniques than strictly relying on numbers that are guidelines. Close is probably OK if you handle it right, but with insufficient care to operator issues, weight safety margins are meaningless.
