Current Picture:

Here's what my trailblazer looked like when I started my modifications:



It was purchased as an '06 TB LS 4x4 from Bunnin Cadillac in Oxnard, CA with 60k miles for 12000.

I was originally shopping for an 01 or 02 Tahoe z71, but when I couldn't find any in decent condition, I started looking at xTerras, 4runners, and jeeps, but settled on the trailblazer when I found the price I wanted for a very new vehicle.

A few days after I bought the Trailblazer, I found our sister site, trailvoy.com, and saw that there was a very dedicated group of individuals who had brought reasonably priced and versatile modifications to the GMT360 platform, and my descent into modding madness began.

After many weeks lurking around on Trailvoy and Expedition Portal, another site introduced to me by the roadie and James Downing, I decided I wanted to begin the first of my modifications. I purchased a FloJet Triplex Diaphragm pump,

a Harbor Freight toggle switch,

various wires and hoses, an add-a-tap,

and the piece de resistance, a portable mister setup:


After tapping into an unused area of the rear fuse block,

I mounted the pump under the rear passenger seat using some bolts, washers, and good old JB weld (no drilling into the metal)

and you can also see where the switch is mounted for the pump. The whole setup still allows a passenger to sit on that seat, with about 1" of clearance from the pump to the seat:


One hose has a garden hose thread on it, which connects to the mister setup, and the other hose acts as an intake for the water (the pump is self-priming up to 9ft). The mister setup gets clipped onto the rear hatch that acts like a shade when opened. This setup should be relocated after other modifications are complete.

The mister system comprises one small part of a larger planned plumbing system, which can be seen in this diagram for anybody curious:

Copied from another post here, I decided to remove my bumper cover and add some lights:



The lights are Daystar #KU80002 lights, 55-watt halogens, and are super-cheap, made even cheaper by the fact that I got them for $20 for 2 from Craigslist.




I mounted them into existing holes on the bumper support, and the simply had a threaded stud that mated with a nut and lock washer on the other side.

Because of the slope of the bumper support, I had to use washers to space the lights away enough to aim them sufficiently upward to provide the desired lighting angle.



They're currently wired through a relay to a toggle switch in a temporary location near the pedals.



All wiring on the lights is covered with heatshrink, and the wiring going into the engine compartment is covered in wiring loom as well.

I also picked up some rubber, 265/75/16 (31.55") Cooper Discoverer S/T's

The review for them is elsewhere in the tire forum.

I also organized my rear cargo area and strapped a spare tire to the roof, since it won't fit underneath the vehicle anymore.

Went from this:

Documentation of CB install:




After deliberating on how to install my 4' antenna, I decided to mount it to the taillight guard after I strengthened it using the insulator clamps a la Roadie and many others. I ended up using a mirror mount from Fry's for around $6 and picked up 18' of cable as well. Using my newly-bought SWR meter, I tuned the antenna (gotta love tunable tips) to 1.2 on ch 1 and 40. Wire runs under the panels on the driver's side, the mount itself is grounded with a strap to the car, and the whole thing is very solid.




Here is the mounting location for the radio itself. It doesn't interfere with my legs too much, and is nice and easy to access. The radio draws power from the cigarette lighter.


Finished product:

Wanting something a little more permanent, I decided to build a water manifold for my water containers.


Here is the manifold attached to my aquatainers, the individual elbows are cemented together with food-rated cement, and the connecting pipe is just friction-fitted. No leaks have occurred, as the water pressure is purely from suction.


The 3/8" reinforced vinyl hose is routed under the seat back to the pump.


Everything terminates and fits nicely under the passenger rear seat. Note the dual coupler, which allows me not only to connect two devices at once (water hose and misters), but also lets me turn on/off the valves to prevent leaks into the car. This whole setup was revised after my Borrego trip revealed some weaknesses of my previous setup.

I've also finally got some pictures of my mister system in action:

Mister hooks up to hose coupler:


Clips on to the top of the liftgate when opened, and that's it!


A moving blanket keeps things from getting too wet


There are a total of 4 nozzles, each using .3 gph, so 1.2 gallons per hour when it's on, and I have 15 gallons of storage.

To improve clearance and reduce rubbing, I further trimmed my wheel well liners in the front, and my bumper cover in the rear.

The wheel well liner is actually attached to the body now, as opposed to being attached to the bumper support in the front.


And here's my rear bumper, thanks to bgwolfpack:
