Plans for my truck include singling short and putting four foot cabinets behind the wheels. New cabinets are expensive so I always hoped to find some good used somewhere...but where?
One day on Facebook I saw that our neighboring fire department was selling cabinets off a fire truck they were reworking. The boxes are 48"W x 26"H x 26" deep. They are heavy duty like you would expect a fire truck to have. I got both of them for $150.
Since my truck is green I'll have to paint the boxes, but that will be a project for down the road. I'll also put Drideck tiles in the boxes like I used in the drom box.
