Looking at DRD for my spark plug upgrade kit. I will be pulling a toy hauler from time to time. 5th wheel. Dry weight is around 12,000. Loaded is 16,000. My truck is a 15 2500 Megacab 4x4 with 3.42 rear end and a 68RFE. The only thing done will be the spark plug upgrade and a RevMax valve body. The valve body is the HD/towing one.

What are you pulling and what tune are you choosing to pull in?
