Heres my 3 totally stock. Keep in mind I was filming but I was either leading or following the F-150 all day. Everything you see him do I did too. My H3 is a base and at the time it had goodyear RT/s tires.

Nice video - Glad you could make it through everything the F150 did. I took mine through some mud (1st time for the H3) during lunch the other day. I couldn't believe how easy it handled it. Better than any Z71 or Bronco I have ever owned/dirven.

 

I used to live way back in the back country in Arizona and needed a 4 wheel drive to get home and cross 3 fords. If you saw a picture of the road home you would ask where the road was. It was always breaking shock mounts on some of the vehicles. I have owned almost every 4 wheel drive made including the FJ40, V8 CJ-7, Pathfinder, Cherokees, Grand Cherokees, International Scout, etc and the H3 by far is the best. A locking diff is much better than a limited slip and the extra 2" of ground clearance i get with 35" tires is a big help.
My only concern is that there may not be parts available if Hummer goes doen so I am considering a Rubicon Limited. I looked at one today and am not happy about the cheap, toy like dash. When I was 7 years old i had a toy dash board that I played with and it looked better than the new Jeep dash. The Rubby is also not as safe , roomy or as comfortable as our H3. I would MUCH rather have an H3 than any Rubicon but will Hummer go out of business? I think I will sell my 06 H3 with only 8000 miles. The Rubicon will need a 3" lift/35" tires because without it it looks like a car, just plain bad unlike the H3 with 35"er's or the 33'ers.
I will also miss the H3 and am hoping Hummer stays around so I can keep it.

 

Here is a pic of mine on the left, it was stock like the one on the right- she just had a Eaton locker but in a couple weeks ago, I wish I would of done that when I got her in 2006, what a difference it makes. I wheeled her like she had a locker, they can do more then you think ! Have fun !

 

The H3 is probably the best off roader stock. Most others you have to modify to get to the H3s level
