Free is good!
Your 4700 (dry) TT will likely be around 6000 loaded with tongue weight in the 600 - 900 range so IMO the Equalizer 4 1200 should work just fine. If your setup feels too stiff, which I don't think it will, you should be able to buy replacement bars, (1000 size, etc.) for much less than the whole setup.
