I didn't have any problems getting at the plugs on my 2003 3.0L. Didn't have to go through fenderwell or any funky tricks. What tools are you using? A large handle 3/8 ratchet can make for a hard job. I have a short 3/8 and a swivel 5/8 deep socket for the plugs. Keep a regular 5/8 deep socket handy for the easier to reach plugs.
