Toolbox

Full time here. My pickup bed starting at the cab - 50 gallon aux tank, 2 tool boxes designed to hang under a flat bed (but they are well sealed so the lids are on top), Hensley BD-5 trailer saver 5th wheel hitch, then nothing back to the tailgate.
Bought the aux tank and tool boxes at Amazon.
Almost forgot, the bed is an 8 foot bed.
