Alright, this is more of a discussion thread than a true recommendation thread. Let's say you had 3k to spend. What mods would you do to improve your truck's on road ability and why? I only ask bec...
My GM 2011 was OK from the factory and all I added were tie-downs and Supersprings. Older trucks had more frame flexing and anti-sway bars can help with handling. New shocks like the Bilstein 5100 can help with dampening of the springs with a camper load.
If you have a spare $3000 another option is going to 19.5 rims and tires which will have less sidewall flex and this while making for a harsher ride will reduce sway a little.
