Suspension upgrades

I too enjoy driving back roads and to make my truck more RV friendly for the heavy loads when the speeds get slow with curves and hills...To keep the truck balanced I installed the 9000 series Rancho Adj shocks for better damping when loaded and to carry that load level for the dips and frost bumps the Firestone rear Air bags with separate shrader valves, Now to control the trans temp better and to keep a eye on it..I put a temp gauge in with the sensor attached to the trans cooler line out to the cooler...Then the line coming back from the cooler I installed a Trans cooler w/Fan a put the fan under the truck bed using HiTemp Hoses in between for the 3' distance and put the control switch for the fan next to the trans temp gauge..works great
