4- The Lockers are the Same 2001-2002 Detroit Mechanical Locker (2003 Eaton Electronic Loacker Takes Over :-))
5- 2001 have the 8 cyl block crack issue check the vin number to verify if it was part of the build issues 137ZA is bad :-)
6- Make sure the Geared hub seals have been changed if over 20K and the brakes are fresh (Expensive job)
7- Make sure you do not have any HVAC issues with the 2001-2002 they still had issues until 2003 (Updated GM Components in 2003)
8- Lastly where I got burned on my H1 was the pwer steering box. It leaks (by design I think :-0) but only needed a clamp replacment. make sure if it leaks you check the clamp.
Anything else you want to know please feel free to ask. If i was going to get another H1 I would not get anything besides the 03 it was the H1's best year mechanically. Those words are right out of a Hummer H1 builders mouth)

Where are you getting all of this info???????
I own a 2001 Open top... I don't believe your post is entirely factual.... never heard of any such power door lock issue,
there isn't anything wrong with the marker lights outboard rather then flush, the LED is nice but both are functional just the same,
2 pc wheels were not offered in 2001, the 17" 2 pc wheels were offered in 2002 for the first time,
the only locker ever offered to a Hummer prior to 2003 was the detroit mechanical locker which I haven't heard of any 2001's having, but the bias ratio in the torsens is different between '01 and '02 but the same '01-'03
the engines in the 2001 are said to be corrected and I haven't heard of any '01s who have had the crack... even with Z engine codes....
mileage is not what intervals seals should be changed at....
the HVAC is the same from 2001-2003 with the only change being the HVAC ducts, the main upgrade was in '97....
please see this link for factual information
to answer the first question.... I tow a 32' travel trailer which, when loaded, weights 10k lbs. Your definatly going to know its back there, but it tows it just fine. I don't travel over 55mph when towing that load though as the temp starts to raise...
