Well, there are several issues that I would like to address.
The warranty:
This is an SVT, so there are some differences in how you are treated and the dealerships you go to. Not all dealerships are capable of working on SVT vehicles. That being said, there might be something in the purchase contract about that. I would imagine though, if you brought up the videos where they flaunt it's capabilities you could get the service manager to do whatever you want. That's how I got Toyota to fix several issues for free on my truck even though it's dirty, beat up and lifted.
The price:
SVT is a premium brand, you pay a premium price for it. The interior and powertrain (especially the new 6.2) are far better than a Tacoma, even a built one. A built Tacoma will never be a Tundra, it's just not a fullsize. You get the balance of comfort and style and appearance. That's what SVT has built as a brand.
The capabilites:
Seriously, what do you expect? Did you think Ford was gonna throw a Class 14 on the showroom floor and say "Go for it buddy"? Get real. They are racing Baja with one as a Class 8, so we'll see how that goes. So you can slap on a coilover and UCA on a Tundra and get the same travel? Ok, so after you spend another $2000 on a brand new truck, you have certainly voided the warranty now. And what happens when you snap a control arm like the AllPros have been having issues with lately? As for the travel numbers, you know that they are reduced so they can be safe right? For example, the 03-04 Mustang Cobras. The put out 390 h.p. stock. For a supercharged V8, that's not that impressive. However, you put a K&N filter and after-cat exhaust, 2 simple bolt ons, and you had nearly 450 h.p. Throw a tuner at it and you're knocking on 500's door. I would say because of the bumpstops that Ford designed to keep stuff from bottoming out, also limits the travel. If you put some air bumps on it, I would bet you'd be over 12".
So, what's this truck good for? Well, it's a bitchin' lookin DD and occasional play toy. It would also be a great tow truck for your race truck. I like it, and if I'm in a place to buy one in the next year and a half, I will probably buy one
