Agree with Otto on the 3000 mile oil changes (even though with a filter you could probably double that and still be safe). Prefer checking trans and diff 3-4 times a year because the trans tends to leak a little toward the diff and overfill it. Outright changes of gear oil only happen with milestone events such as swapping the 4.11 for the 3.55 which I did last week.
It's a little off topic but just gotta say the 3.55 with 235 seems a match made in heaven.
Also have a set of tall 16" tires and a set of 15"s to adapt for highway or city/mountain type driving.
