It has come time to replace some of our truck beds as some of them are so rusted, they are unsafe to stand on let alone have a 300gal fert tank attached to them. Currently we have 4 01 f350s that will need a new bed eventually. We have tried beds with and without spray on liner. Seems not to help and have to change beds every 4-6 years. Has anyone tried a wooden stakebed/flatbed? I know you can get stainless framing. I just hate to spend $1500+ on a new bed that will have to be replaced in 5 years. Also a wooden flatbed could be used as a sander truck in the winter. What is your take on a flatbed?
