Only have 28,000 miles on the '05 D-Cab and the seat looks "crushed" and when i get in or out the height adjustment is pressed constantly leading to adjustment to raise the seat...it was not like this when new leading me to believe the construction or type of padding is inadequate. Tried the search but no luck in getting info if anyone has approached the dealer concerning this issue and if so interested in hearing about the results.
Thanks

your habit of sliding out of the truck is the problem. It happens on all brands of trucks. step boards and a new style of departing is your best solution
