I like the NEVER STOP EXPLORING stickers that one of our fellow forum members makes/sells. Seems like a simple but appropriate mantra for 4Runners and 4Runner owners.
Other ideas for your 4Runner:
BLACK RUNNER (Use BLADE RUNNER font on this one)
4RUNNER 4EVER
4RUNNER 4SURE
4RUNNER 4GET IT
4RUNNER 4NICATOR
BACK IN BLACK
4RUNNERS EAT DIRT
4RUNNERS EAT DIRT 4 BREAKFAST
4RUNNERS & CHARGERS RULE
4RUNNERS & PADRES RULE
DEATH BY 4RUNNER
4RUNNERS IN MIRROR ARE CLOSER THAN THEY APPEAR (Obviously text fits on 2 lines)
4RUNNER FANATIC
1999 T4R HIGHLANDER
HIGHLANDER FROM HELL
PARTY LIKE IT'S 1999
1999 WAS A VERY GOOD YEAR
OL' SKOOL 4RUNNER
TOXIC TOYOTA T4R

If you or anyone else wants custom stickers, I have a cutter and I can make die cut stickers. I've made a lot of TRD, toyota devil horns, etc. pretty much anything you want. If you come up with an idea let me know and I can make it for you.
Hey [MENTION=91297]Kraze[/MENTION], where did you get that switch plate that you modded to the front of the radio pocket? I had one made that I'm doing the same thing as you but yours is the only one I've seen actually done that way. Nice work man. Any installed pictures?
That would be me, haha. [MENTION=82211]TCMach[/MENTION] got one from me for a windshield banner:

Haha it was actually the sticker you did for TC across the windshield that gave me the idea of putting one on the windfairing! I do love that sticker.
So far I think the ones I'm leaning towards are:
I Hate Stickers
Not A Jeep
Jeep Recovery Service
I think those ones would be about the right length at least. Decisions, decisions.
