Sheldon, just a suggestion. Even if the dealership tells you there is nothing wrong with the truck you should still get a record of your concerns for later, just in case. The more you complain about it the better it will be should something go wrong down the road. So take it in as often as you can and make sure there is a repair order written each time so you have a written record of your complaints. Also works well for "lemon law" cases.
