If the trucks didn't rust out after 6-10 years, how could they sell you another $50.000 truck?

Now they are adding foam and liners to the back of the sheet metal and in the rockers & pillars so new pieces can't be welded in to repair them. How would it be of any benefit for any manufacturers to build trucks that lasted much longer then the warranty? They only make money off those trucks from the 1st sale, any repeat sales cost them income.

The manufacturers best interest would be to sell you a new truck, have you return to them for all of the required maintenance, then have it self destruct a couple months after the warranty expires, so they can start the process all over again. Gene
