My brother Josh and I welded a new bed on his dt466 dumptruck. It was a pita, but worth it for my bro, bra. we used 3/16 inch walls, 3 inch channel and 2 inch angle iron to construct the monster. The total cost of steel was around 1200 bucks. wow. through the whole project we only had 3 casualties, a harbor freight angle grinder...which is expected, a 5 year old craftsman 26 gallon compressor and the worst was my baby, millermatic 175 welder, it only needs a new gun to be back in action.
P.s. Nothing compliments a tattoo like a cutoff tshirt.
