OP if it were me, I'd find another tow vehicle or put this one back to stock. Sure, it might physically tow it, but a lift kills towability. You may still be within your numbers but the experience is likely to be uncomfortable and frustrating with anything much larger than an rPod. If you have 3.21 gearing running 37s, forget it. But... if you want to try it, by all means. Sometimes experience is better than anecdote.
Lifted trucks generally aren't very tow friendly (coming from someone who had a lifted truck at one point and that towed with it).
