I ended up buying a V8 '06 4Runner.
I wound up buying a V8 '06 4R as most of you suggested. The hitch receiver may be aftermarket, as the label on it says,
"Capacity when used as a weight carrying hitch: 7300 lbs. Max Gross wt, 730 max gross tongue weight."
And "Capacity when used as a weight distributing hitch: 7300 lb. Max gross tongue wt, 1095 lbs. max gross tongue wt."
"Consult your owner's manual for maximum towing capacity and recommended towing proceures."
