JCR welded up my Explorer's 8.8 a few years ago. It's still holding and it was a DD for probably 25k. You will go through tires FAST. I mean really fast...it's crazy. It's also slightly embarassing in the gas station and supermarket parking lots. Oh well.
I had ruined the Detroit Lunchbox EZ Locker that was in there before somehow. I have heard good things about the Aussie Lockers from the Explorer guys though.
