Hi guys

I'm overdue for a tune up on the trailer tower. She's a 2001 V10 with 63000 miles. I had some nasty rats build a nest under the hood and chow down on my plug wires and destroy the hood insulation. Im taking it to my local dealer for plugs, wires, radiator flush and hood blanket. I recently had the tranny serviced and all the gear boxes done. Never had a tune up or anything done before. What am I missing? Anything else I should have checked out?

Thanks in advance.
