Removed tank from cab. Want to continue to use my truck as mostly just an ole truck, with some nice modifications and updates here and there. So, I would prefer not to fill tank through the bed. I am looking at an underbed tank that has side fill option. It looks like I could run the fill tube out through fender. But I would appreciate hearing from folks who have already done either the above or some other out of cab tank placement and no through bed fill. All help appreciated.
