All the guys on here are correct, go with a WDH. Either the Equalizer or Dual Cam at 12000# would be perfect. Rather have plenty of support than just cutting it close and the price difference is really non. I personally went with the Equalizer after much research. I liked how it connected and with my V-Lite, it was a better system because of space. They both have great reviews online. Good luck and enjoy your new TT. You won't regret the purchase.
