I'm getting ready to change to syn. oil soon. I have a new truck with 3300 miles and want to make the switch. Any concerns?

No cocerns.  Remember, lots of engines come with syn like Mobil 1 from the factory!  I changed my 2007 Frontier over to Mobil 1 5W-30 at 1100 miles and have used it or the EP vrsion ever since.  I now have 25,000 miles on it and burn no oil.  However, kkep in mind that you are under warranty and need to keep to the factory recommended oil change intervals to maintain warrany coverage.  Syn will give you better low temp starts and perhaps a bit better mileage.  Mobil 1 will also keep your engine VERY clean internally.

Also, use a good filter like a Wix, a NAPA Gold (Wix), a Pure 1 or a Mobil 1.  Pure ! or NAPA Gold have both worked very well on my truck.

You should follow the OWNER"S MANUAL on oil  change frequency while you are under warranty and keep receipts for what you purchase as well as a log book.  I use a stitched log book where the pages cannot be removed.  I attach all receipts for oil changes in the book where the oil change is recorded.

If you have a warranty claim and don't follow the oil change schedule, you may have the claim denied.  Your call.  I have always used Mobil1 in all my vehicles and while under warranty, follow the owner's manual.  I buy my oil at Wal-Mart.  You can go up to 7000-75000 miles on oil if you do a lot of highway driving.

However, with modern oils there is NOTHING wrong wth conventiomanl SN oils at all.  Why not use Mobil 5000 or Pennzoil Yellow Bottle 5W-30?  They will do fine for you on a 3000-50000 mile oil change.
