I have recently purchased a 2013 Dodge Ram Diesel. I thought it was coming with the 5th wheel tow package but it did not.

I have purchased the after market package from Mopar however my dealer is uncertain how to install it. Does anyone have any advice or instructions? They are talking about taking the box off my truck?

Curt makes the legs that will fit into the puck system now so i wouldnt have rails in my box
