I've owned dozens of truck tool boxes. On my 5.5 ft truck bed, putting in a tool box makes it 3.5 ft. then how do you haul plywood or an ATV? I've always wanted as tonneau cover to keep cargo dry and secure along with better fuel mileage. Crossover tool boxes are hard to reach on full size trucks. So how about a sliding tool box that comes out to you at the end of the tailgate? It's called Unruli, to remind you a free spirit can get organized. https://www.stayunruli.com/ #unruli #MrTruckReivews
