I'm pulling an 8K lb TT (not the one in my signature)with a 2011 Tundra, 5.7L, 4:30 gear and it does everything that I've asked it to do. It pulls at the sweet spot, 60-62 MPH all day long at 2000RPM with 6th gear locked out. I don't think anyone makes a better 1/2 ton truck. If Toyota ever builds a 3/4 ton truck, I'll have one.

I now have a Keystone Outback, but I try to help when I can.
