I've replaced the rear bumper with a much straighter one and I haven't been able to find a splash guard yet. I never even looked at the power antenna, so it may be bent, but it does work. I do have the rear seat headrests. The red is a repaint from sometime in the mid 90's. It's not the best, it looks better in photos than in person. The clearcoat is peeling and is mostly gone from the roof and hood. Hurricane Ike took alot of the remaining clear right off. I'll probably repaint the truck in the next couple of years.
The truck is stock and I plan on leaving it that way. I use it as my daily driver and for camping and hauling stuff that won't fit in the wife's car. I have only taken it offroading once, and that was really just very light duty stuff. I may pull the running boards off as I think it would look cleaner w/o them.
I've never been much of a truck guy, but I just love my 4Runner. It's not to big, not too small, it's more comfortable than I expected and I really enjoy driving it with the top off when the weather is nice.
