Semi-Home boy!
JJ, (checked your profile - is your 1st name Joe?)
1st - Welcome to the TDR, it's a great place!
2nd - I just can't see taking my lawn mower to any dealer let alone my expensive truck. In your case, however, if it's under warrenty go for it but, as somebody mentioned watch em` like a hawk! Talk to the Svc. Mgr. and tell him you'd like to watch the mechanic work on your new baby. If he gives you the "due to insurance reasons you can't enter the work area" bit, tell him you'll sign the waiver. If he tells you there isn't a waiver tell him goodbye! Where'd you get it Dealers Name. You may wish to post a question to the TDR about them to see if the other guy's have any experience with them before giving them your new truck?
3rd - I agree w/previous posts and also use Premium Blue & Fleetguards on my 99. Do my own oil changes and everthing else - so far. As far as getting the factory filter off, my experience is as follows: purchased w/72k on it but, from a Dodge dealer whom changed the oil & filters prior to me receiving it. Got it home 150 miles later, checked the oil, it was high by 2 quarts

. Quickly drained it off to the correct level. My first oil change the filter was a bear, knuckle head mechanic didn't oil the "O" ring prior to overtightening the filter. Get yourself one of those (not sure exactly what they are actually called) filter pliers. They work great and fit almost any size filter. Make sure you torque the drain plug.
You will see varrious opinions about types of oil & filters here, all good information but, in the end it's up to how you drive and wish to maintain your truck that will help you decide.
4th - Look in the back of your Owners Manual and spend the $90 bucks on the DC Shop Manual. This is a great site and all that but, nothing beats a real reference book with instructions and pictures.
5th - (and hopefully final) Where is Gibbstown, NJ? I'm in Levittown, PA which is about 2 miles from the NJ/PA turnpike? I think you are the only person I've seen on this site that is close to me. Drop me a PM with more details on your location if you wish.
