Here's my tough 2006 Toyota Tundra Double Cab. Let me know what you think.

Aside from the factory options of Bedliner and Fog lamps, I have outfitted my truck with several other exterior aftermarket additions:

1) Chrome Step Bars from Go Industries
2) Chrome No-Drill Bed Rails from Jammy, Inc.
3) Bug Shield from Lund
4) Aluminum Skid Plate, aftermarket no name
5) Window Tint From ARC Audio
6) Bilstein 5100 Shocks
7) Nitto Terra Grappler Tires

The factory stereo wasn't too hot so I went all out and made a serious Stereo upgrade - and I'm not talking about that BS JBL cr@p either. Here's what I had to do:

1) Eclipse Flip Face CD 8445 Head unit w/ iPod Hookup
2) Diamond Audio D661 Components in the front doors/pillars
3) Diamond Audio D362 Coaxials in the rear doors
4) Dynamat kits for each door speaker
5) 2 Diamond Audio D308 8" Subs in a sealed fiberglass box under the rear seat on driver side
6) JL Stealthbox (10" sealed) in the center console
7) Alpine MRP-F600 Amplifier - The Diamond 8's run one channel series/parallel and the JL 10 is on one bridged channel.
8) ADS P450.2 Amp for the full channel speakers
9) Hornet Alarm

Here's a pic of the sealed box for the Diamond 8's

The install, as you can imagine, came at no small cost, however I have a fully customizable sound that is great for most any type of music. As most DC Tundra owners can tell you, there isn't much space allowed for subs in this truck. I pretty much maxed it out w/ the three subs and 2 amps which are all hidden, unobtrusive and nearly impossible to steal.

The Stealthbox is crossed over (low pass) at about 55 Hz so it handles the really low stuff from about 30 - 60 hz. I have the 8's playing as low as they can (about 45 Hz) but upped their high end cut to about 200 Hz to get a smooth transition to the mains which allows for the whole system to play louder and cleaner. The 8's share 1 bridged channel of 300 watts RMS @ 4ohms in a series/parallel configuration which was requirred for the DVC setup.  The JL 10 (singe voice coil) get's another bridged channel with a full 300 watts RMS @ 4 ohms.  The amp is pretty mena so it only needs gains at about 1/3.  I can get hard thumping bass, smooth mids and crisp highs without loosing any clarity.  Its an SQ setup.  You won't hear me a block away but it can get pretty screamin loud with no speaker distortion or amp clipping.

Recently I added wheel spacers, upgraded the tires, and put on new front shocks. 

Because the stock wheels don't have much offset you can't get a much bigger tire on without getting new wheels or adding wheel spacers.  I like the factory wheels and getting spacers was cheaper than new wheels so I opted for the spacers.  I got 1-1/4" spacers from Wheeladapter.com and that allowed me to upgrade the tires to a set of Nitto Terra Grappler 265/75 R16's. 

To get good clearance in the front with these new tires, I got a set of Bilstien 5100 Adjustable Shocks.  They are set at 1.5" lift (they can go to 2.5") which gives me about 2" higher front end when you consider the tires.  This really evened out the rake without the need for a leveling kit.  The ride quality did not change drastically.  if anything its better now.  And with the new ride height and wheel spacers I can turn full lock without any tire rub on the suspension.

As for the truck itself, you just have to own a Tundra to understand what a badass it is. I have put well over 1 ton of cargo in the bed and hauled it 150 miles with no problem. In fact, this truck rides better with a few hundred pounds in the bed, rather than empty. That's not to say that the ride isn't great to start with. Wth everything from bricks, concrete, sand, cinder blocks rebar, and lumber as a payload, it has never missed a beat. This truck runs strong but feels nimble and docile when you need it to. It is reserved and classy when it has to be... even my wife loves driving it. And yes, I know the 2007 is a bigger, tougher truck, but I didn't want a behemoth to drive, just a fun truck small enough to be a daily driver but big enough to haul people and loads of stuff... that's what I got and I love it.

I'm waiting to hear what everyone thinks.
