I have had the Doublecab blues for a few years now, I want one so bad but I chicken out every time. I have found around here anyway that a 4x is pretty rare and people want alot of $$$ for them 2x or 4x. If you get one do me a favor and tell me it sucks and you hate it that will help me sleep at night.
I've seen quite a few people converting the pre-runners to 4wd when they sas their rigs. In fact, for tacos, IMHO, I'd rather start w/ a 2wd pre-runner double cab and swap to right hand output and marlin duals (+sas) to have pure gear driven t-cases. of course, this would be after I won the lottery...
