Re: Rubicon Thoughts?
Some people won't be satisfied with it regardless of how tits it actually is. None of the major car manufactures will ever tool up to build an ORV that you can slap a set of 38's on it and go terrorize Moab. Those Jeeps will always be "built, not bought."
However, like you said, the Rubicon has many parts that you will have to get from donor vehicles and aftermarket sources. But unlike a homebrew job, the Rubicon is engineered by dudes who do this for a living; so you get a vehicle where the systems are designed to work together.
Not only that, but a current TJ (with optional 44 rear) with a swapped in 44 front, lockers, and 33's probably has several thousand dollars invested. Yet, if the owner ever sells it, almost all the mods are losses because 1) People who want a TJ with a 44 front, lockers, etc generally want to do it themselves so they know its done right and with components that they want. 2) Modified vehicles are more prone to breakage than a pavement pounder. 3) You lose the money invested in labor. On the other hand, putting a Rubicon up for sale will not have those issues.
A lot of questions can't truthfully be answered until they are actually in production, and have been truly tested by guys not afraid to beat the heck out of them. Maybe the lockers turn out to be complete crap, the rumored D30 knuckles on the 44 housing are a major weakness, and yadda yadda yadda. So people would claim getting aftermarket stuff would be better.
I don't know if thats what you're getting at, but those are my 2 cents.
