I'm probably the only dummy that would make a big deal out of replacing the dome light on my 2001 quad cab but here goes. When I started tugging on the dome light to get to the bulb it felt like I was going to break something in the process. What I learned was don't just pull down on the dome light. Slide it toward the passenger door as far as it will go and then drop the drivers side down. EZ. Then the bulb retaining assembly lifts away from the fixture in one piece.
