Truck runs good but there have been some problems. The brake light goes on most of the time, brakes are in working order says dealer. I need plenty of distance to stop. Gas gauge goes up and down intermitantly if you fill-up, at 1/2 tank it will go away. I have racks and boxes which has made body panels break away at tailights. Pro-grade not. Response was too much weight on bed? Vibration or shudder on launch. Mechanic found bearing in tail of tranny is worn. Remove to repair, too much weight?. Engine knocks on start still, response was could not replicate. Taigate cables were only repair that was correctly solved. The rusty bumper+driveline clunking was ignored.
The 5.3 motor and locking differential are working still (knock knock).
