Anyone running a MOON style tank in the box?

[IMBROKEN]

Hi guys,

I was wondering if anyone was running a MOON tank or MOON style tank in the box of their truck, and how they like it? I was looking at going that way as the fuel cell behind my rear axle is bumming me out. The previous owner installed a fill neck on it that comes into the rear fenderwell, right behind the tire(like right behind, it almost touches). Its a pain to get down on 1 knee to fill it, and the only way I can tell the cell is full is when it runs out the vent and onto the ground at the gas station. I was considering just replacing the cell with another and adding a trap door to my box floor, but I wanted to see if anyone else is running a MOON style tank. Thanks everyone.
