Heavy gauge steel bent on a break a Greer tank and welding with the end caps, axle, tires. We got tired of flimsy meat trailers from the store so had this made and then moved to soldotna and I no longer have a steel shop. Weld it together and have a meat trailer that will last forever. Had this made years ago but it’s been stored in the connex. With the cost of everything I’m sure this would cost way more today. $950 obo or trade for copper thrower
