Ideal for those who want to utilize their semi tractors and not add another tandem truck to their fleet. This trailer will carry a 3,200 gallon stainless steel or poly tank. The standard model includes an I-beam main frame, 18' long x 34" wide bed, 22,500-lb. axles, dual radial tires, air brakes (with ABS and auto-slack adjusters), and a Hutch leaf spring suspension. This trailer can be converted to an equipment trailer by adding full decking, rear ramps and a beavertail.
