I am trying to find a good techician that is experienced with these trucks. I have a 99.5. I think it is making some strange sounds but would like someone that is far more experienced than I to look at/listen to it. Fuel mileage hasn't changed, but it seems to have a tapping sound it didn't have in the summer. Truck only has 63K on it. I just don't want it to turn into something worse, if it is anything. I hate to take it to the dedalership and I know there are a lot of guys here that are very experienced with these trucks. I live near Frederick in Mount Airy. Thanks in advance, Tom
