Getting my new 2002 TM Home

I have a 2008 Chevy Trail Blazer:
tow capability.: 5400 lbs.
Axle Ratio: 3.42
GVWR : 5550
GCWR: 11500 lbs.
Hitch Weight rating: The weight-carrying hitch limit for TrailBlazer is a 4,000-lb. trailer with 400-lb. tongue weight.

We will be towing a 2002 2027SL TrailManor: (Being purchased out of Riverton Utah)

Towing Length: 20’3”
Approx. Dry Weight: 2865 lbs.
Approx. Tongue Weight: 392 lbs.
Approx. Load Capacity: 1210 lbs.
Approx. GVWR: 4075 lbs.
Single Axle

I live in Tucson and am picking up the TM next saturday (4-26-08) in Riverton Utah. My trailBlazer has a Hitch assembly
I need:
1. shank assembly
2. Head assembly
3. Spring Bar assembly
4. Chain and Bracket assembly

Any recommendation on brands? I understand from reading various threads that I don't need sway control. I will be getting a P3 brake controller.

Should I do this here in Tucson before leaving or wait until I get to Utah to have it put on?

so much to do so little time
