Hey everyone. Another noob here. Just wanted to say hi! I drive a decently built 2006 6.0. Still in the process of buildin her though. All I have left on my build goal is throwing in some better Axles and doin the T-case. Gotta through a new AirDog on there and a return system. Then just going to choose if I should do Natural Gas, Propane, or Methanol. Any thoughts on which of the 3 are better?
