This is a replacement post from about one year ago.

I've had this power inverter for about three years that I had intended to mount in my truck.  I bought it on clearance at Tractor Supply for $80.  It has set in its box in my garage ever since.  Everytime I thought about WHERE to mount it where it wouldn't be kicked... get water or mud caked on it, etc... I kept coming up empty.  Our trucks are just... SMALL inside.  Driving back north from Tennessee, out of the blue I  remembered a tower computer case that I had gutted the inside that was sitting in my garage.  Hmmm?

When I got home, I drug it out.  I set the inverter on top of it... and it appeared to be the perfect size.  It was also a doable size to straddle the existing console in my Tracker.

So I got to work building an internal frame that would further stiffen the case and provide a strong base to attach the inverter to.  I used strap steel to build this framework very snugly inside the computer tower case.  The console had to be sturdy because my 87# boxer uses this area to perch his huge ass when he is riding with me.  He's a hog.  O.K.... a LOVABLE hog!

Next I trimmed the computer tower case into a size that would easily sit across my existing console.

This new case was going to replace my existing factory fold-down arm rests too, so I fabricated a large pad for the top of it using a couple 2X6 boards cut down and glued together.  I heavily rounded the corners so they would be easier on the elbows while driving.

After I had the arm rest shape right, I assembled the pad base, the computer tower case and the frame, inserted the inverter, marked the place where the inverter mounting holes would be and drilled holes through all of it so it would sandwich all the components together with four mounting bolts when tightened.  I installed "T" nuts into the top of the arm rest so these four bolts would thread into the armrest and secure it and the whole assembly together.

After all the assembly and a couple of test fits... I took the new armrest (along with my factory fold down armrests) to an automotive upholstery shop and had them cover all of them with a heavy gray vinyl that matched my leather interior (pretty close anyway).  I had them add an inch of very dense padding to the top of the arm rest and they rolled it down around the sides of the pad area as well.  It turned out to be the perfect pad density for an arm rest this size.  It's very comfortable on the arm.

I assembled all the components to see how it would look with further work.

Next was wiring the inverter to my power source.  I bought a Buss brand 25 amp fuse block and mounted it to my driver's side fender under the hood.

To run the wiring, I found an unused grommet in the fire wall to the lower right of the brake master cylinder as you look inside the hood.  I popped it out, inserted a rubber grommet and I was good to go.

The inverter is rated for 1,000 watts and 15 amps.  10 gauge wire will safely carry that maximum amperage up to 10 feet... so that is what I used.  I found some small rolls of 10 gauge came in 8 foot lengths while others came in 10 foot lengths.  I bought the 10 foot lengths and it worked perfectly.  It is better to have to cut off 18 inches, than have to add wire length and have another source of corrosion and connection issues.

I wrapped the wiring in a plastic loom for additional protection then fished it along my factory console UNDER the carpet, up and over my pedal assemblies and out the hole in the firewall to the fuze block.

Next I spray painted the computer case to a gray to closer match the upholstery and did the final electrical connections so the inverter was hot.

I also elected to add a couple of extra 12V accessory plug-ins under the inverter because you never seem to have enough of them.

My battery had aged over six years so I also decided to buy a new battery.  I bought an Optima yellow top.

I flipped on the inverter switch and I had power.  I ran my 3/8ths inch drill off it and it worked fine.  So I now have 120 volt power supply in my truck to run computers and other devices when and where I want or need to... and finally got that inverter out of my garage.

I lost the little storage box and the rear cup holder with this mod, but I can live with that.  I didn't use the storage cubby anyway and the cup holder can be replaced elsewhere.

Disclaimer:  My Tracker isn't a GMC Denali... It's a little tin box Chevy Tracker that is now going on 14 years old that I have modified more than a few times.  I have no illusions.  It is what it is and because of this, adding these mods doesn't produce a guilt trip of "trashing" my truck.

These trucks are both a hobby and passion.  Plus they serve most of us as our daily drivers as well.  They are like space ships that take us where most others have not gone and many could not even go if they wanted to.  I like my Tracker for these reasons.  These type small trucks and these type modifications aren't for everyone or every vehicle.  Only those with the sickness.

nice.  creative and recycling and one-off.  good work
