Thanks Dick, I see that you are not too far from Waterbury, I have been at GMCR In TN for 4 years.
I have 10ply tires on my truck max out at 80psi. If they go down to @ 65psi Starts to look like a car tire does @15psi. Really low. Everything as far as the truck is concerned is still all factory. no suspension mods at all. I will revisit my shocks as you suggested. My truck is a long bed 4door dually ride is not to bad.
