That's one NICE tank/toolbox combo BigBlock!
I really like the color-matched look. I'm not sure I could afford to fill up THAT tank, though! It's all I can do to keep my truck full, much less the little (36g) tank in the bed!
One thing to consider if anyone is planning on putting a pump w/ hand nozzle on their tank- you might wanna leave about 3 inches between the tank and the front of the bed so you'll have enough space to store the hose. Helps to protect the hose and keeps it outta the bed. Gives it an overall cleaner look. Just my $0.02
