My wife just bought her new 03 Trailblazer 4x4 home last weekend.  It's a Indigo blue LT-the only options she got were running boards and upgraded BFG tires.  Nice smooth ride and great engine (4.2L I6)!  :thumb:

 

What kind of mileage should we get after it's broke-in?  She checked the first two tanks and it was about 16.5mpg mixed driving.  What should it get on highway?  

 

Also, has anybody that hangs around here towed anything with their TB?  I'm going to use it to pull my utility trailer after a few hundred more miles and I'm curious to see how the engine does with about 2000lbs behind it.

 

Last; were we supposed to get a wire harness for a brake controller with it?  My 01 Silverado had one included when I bought it and so did my F250.  I can't even find anywhere if it's pre-wired for electric brakes and I haven't had a chance to look under the dash for a plug-in unit.  Anybody ever look into it or have a brake controller installed?

 

Thanks!  :chevy:

What should it get on highway?

While on a trip from south Texas to Washington state I went though Yellowstone National Park. I filled up just before entering the park, went though on cruise control at the posted speed limits, which were quite slow because it took all day, stopped numerous times for pictures and such. Filled back up after we got through Yellowstone and doing the old trip odometer miles divided by fill up receipt gallons it came out be a little over 24 MPG so no DIC trickery either. I was shocked since we were no where near highway speeds. The averages during the trip outside of Yellowstone varied between 19-22 MPG. All of this mileage was done with the odometer starting at 2,081 miles and by the end of the trip I had 9032 miles on the odometer. Of course lately I've only been getting 13-14 MPG but I haven't gone on any long trips recently either.

Also, has anybody that hangs around here towed anything with their TB?

I haven't towed anything myself but have heard nothing but praise for the triplets towing capabilities from other owners. Good to see that you'll wait after a few hundred more miles, as it's often suggested to wait till you get past the 500 mile break-in period.

Anybody ever look into it or have a brake controller installed?

There's a 4-wire harness attached to a large harness under the left side of the steering column. Remove the lower fascia, 2 vertical facing screws on a Trailblazer, the wires have a white tag wrapped around them and is taped the larger harness. These wires are connected to the controller wires ACCORDING TO THE BRAKE CONTROLLER INSTRUCTIONS, do not match the color of the wires, the connections and colors vary with manufacturers of the controller.

 

Also here's a couple of fan sites you might find interesting.

Congrats on the new truck. Pics?

Thanks for the replies.  Bravada-if I can get 20+ mpg I'll be more than pleased with it.  I won't need the brake controller anytime soon-just curious.  My 5x8 is 4-wire plug and no brakes and I don't want to use it to tow the enclosed trailer-it's weight would be pushing the limits of the Trailblazer's tow rating.

 

I'll get some good photos soon.  My wife doesn't get home with it until after dark the next few days.   Actually I've only gotten to drive it twice.  So far I'm impressed.  The build quality blows away the old S10 Blazers we owned.  I just went out in the garage and took a few quick shots of the cab and motor, I'll get the exterior when I get it washed up and catch a sunny day:

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
