I am new to TDR and to towing and am planning on purchasing a 32' fifth wheel soon. I have been getting my truck ready and reading alot of great advice, but I still have a few questions. I am stock now and do not plan on bombing it, yet... ? What gauges make sense for the 6-speed 04. 5 3500? Especially when towing. I plan to add a PacBrake and a BrakeSmart controller.
