If you do a search, using "tank" as a "subject line" search you will find this is a often debated topic here on the bolt.
Fact is there are legit reasons to move the tank, that is why many choose to put a tank in the rear of the frame.
But moving the tank is a personal thing. I moved mine for the room I gained behind the seat and I feel it is safer not having the tank in the cab. If you would like to see how I did it check out my build thread below.
Do whatever makes you happy, and that will be the right decision.
Good luck!
