My 1999 F250 is starting to show it age. With over 210 thousand miles the leaf springs in the back have lost some of their bounce. Also the trailers I am towing today have a higher weight then when I started. Last summer I noticed that handling was getting soggy and I had to be careful not to get the trailer swaying. I briefly considered replacing it with a newer F350, but as the truck is otherwise in good condition, choose instead to upgrade the load capacity to around what a new F350 would have.
