We had this trailer built to facilitate transporting the planks, which weigh I would guess about 300 to 400 pounds each, from the jungle. We drove into Pucallpa to a metal shop with a hand drawn sketch one evening and it was ready for us the next evening. John and I built a bed and sides for it. Now instead of it taking four boys to haul one plank out, two boys pulling this cart can haul two or three planks per trip. (The wheel is an amazing labor saving device)
