Thanks 656mx. No, I never tried pulling the fifth wheel since I have a few other trucks and a few months ago I traded off my fifth wheel for a bumper pull toy hauler. I wanted a 4 inch lift but couldn't locate one fast enough so I just ordered the 6 inch.

Let me know how that 47re works out for you. Do you have a build thread?
