Heads up for tow vechicles

Some folks have the wrong idea of my info. The truck is a '06 F-350 Dually LB with 146,000 miles on it. It spent many years up North in the "rust belt". The bed in in perfect condition. what I am trying to do is inform other owners that the supports for the bed are prone to rust. The end and middle beam are affected. The support near the cab is not rusted. I am going to a few welding shops next week to get estimates on the costs for new supports to be welded onto the bed. I am told that it would be no greater than $2K. The break lines were inspected and purged. Just had major work done on the truck: A/C line leak, rear left caliper frozen, new alternator, tires rotated, new shocks. Still beats buying a NEW or USED (someone else's problems) truck.
