My biggest regret is getting a regular cab. I have a 2008 sierra that I got for a great deal, but if I truly want to go fast I'll build my camaro to go faster that way come race day I'll be able to pull the car while bringing my friends along (once I pick up a new crew cab). Besides, who says you can't make a crew cab go fast? Just add more power!!!

 

You have to ask yourself what you really want out of the truck. If you are just going to DD it and actually USE IT as a truck, than I'd get the CC. If you are going to build it up just for some fun, than RC.
