My buddy and his uncle been debating about going carbon fibre for the Saum. We'll just finish installing the new rack and bakflip tonneau covers for kayak mount on his truck. I believe too the extra length should give a good difference.
One old guy brought his 2005 Ram 2500 to the shop for new shocks and nerf bars installation. He said he had dealt with black smoke all the time since the 2nd year of ownership, hence it is a good running truck at close to 200k miles.
