Hello, I am looking at a auxiliary tank/toolbox combo for my truck. I have a long bed so the width (bulkhead to fenders) isn't a issue currently. If I were to switch trucks down the road, I would like to have the ability to transfer it to a short bed. Does anyone with a short bed know the measurement or maximum width tank that will fit? I'm guessing somewhere between 18"-20". With the price of these things I want to have options. Thank you in advance.
