TT4?

[Buckeye Hummer]

I haven't experienced any problems with ABS yet and frequent steep climbs and descents. I have found that the gearing has been sufficient to crawl down a hill in Low Locked 1st gear, sometimes too slow. Even with ABS my truck did slide on this decline (they locked) so I hit the gas to correct the rear and the truck righted itself. I've been out with a number of 99-02 H1's and they have all done fine with exception to a couple running with GSA's that would slip going uphill. My '03 has rear locker that has been sufficient for everything I have encountered thus far. It is my opinion that the tires are probably more important than anything and should be considered before lockers. Here's a pic of the slope I was slipping on:
