Here is a thread explaining Axle options without breaking the bank. There are grear reduction and transfer case options in the thread also. I think building a stock king hauler kit to figure out how everything generaly fits together and then take it apart and start working with a fresh frame is the best way to aproach it. Make a build thread in the truck section so all of us can see your hard work and we can help you!
Something like this?
