I have a 2015 F-250. Been treated with a couple of sprayed rust proofing products over the years. Now in DE it's hard to find someone who sprays the rustproofing products. I work from home so I try and avoid driving the few times when the roads are salt or brine treated. I just upgraded the HPFP. Keep up with suspension and brakes. Get outside detailed 2x a year. Don't let wife or kids drive it. Don"t get into the vehicle with screwdriver or putty knife sticking out of back pocket (did that in another vehicle and you can guess the result).
