Just wondering. Thought you could only get it in a ext cab or 2500.

 

you could if you wanted to put one in there. othewise, they didnt come stock. nice challenger

 

only if you make one like i did or others

 

If you have enough money to put down (a lot), if you talk with GM, they may make one especially for you. Though I doubt it. Of course big money talks, but it would never be worth it. The only thing you would have to show for would be that you would be the only one with those options straight from GM.
Just buy a RCSB truck with a 4.8L in it, and do a 6.0L swap later. It would be cheaper of course to buy the 4.3L, but the 4.8L will make for an easier swap.
