Hello,
I'm glad I found this forum, I've been going through a lot of the old threads and it seems great.
Can anyone offer me some advice on my 2001 H1 Wagon?
- How do you aim the headlights? I see that there are 2 screws of 2 different sizes each.
Tighten and loosen the screws - if it goes the wrong way, reverse the direction you are turning that screw
-What is the best air pressure for street driving and should I adjust the pressure for highway driving?
Depends on the tire. I actually had best luck with GSA's at nearly 50psi.
I run wider off-road tires at much lower pressure to get even wear - most around 25psi. Tell us what your tires are and you will get more specific answers.
- Is there a good place for accessories? I'm looking for racks for over the wheelwells and the console between the rear seats. I found Teakatoys.com but their prices seem really high. (they are almost 100% more on the husky cargo liner I bought)
It really depends on what item you are looking for, but here are a few to go browse around at:
Adventure Accessories (Lynch Hummer)
BlueHummer Outfitters
Rubberduck4x4
Predator Motorsports
And of course, anyone else who advertises in either Ultimate Hummers Magazine or on
http://hummer.offroad.com 
- (yeah, so I might be biased since they pay some of my bills).
-Why are the running light cutouts on the hood assymetrical?
Military blackout light mounts in the "extra space" on the driver's side on HMMWVs - they share the same hood as the civilian trucks.
Thanks, and I'll look forward to your answers and to being an active member here.
