Yes, the Big Tow is a Class IV. That's the only way they can specify a 940lb. tongue weight as well as a 9400 max tow capacity. As seen on the chart I linked to, that is near the max of a class IV hitch.

I think your idea to borrow your relative's truck is the best move. As much as we love our Titans, they are still just a 1/2 ton truck.
