This is the second trailer we are selling due to downsizing our fleet. This trailer was also used daily through the first week on 2017. In April on 2014 we had Bluegrass Tank in Elizabethtown, KY completely replace the frame for the suspension at a cost of $9500. They used stainless steel c-channel to fabricate the frame out of . They also replaced the axels, brakes, drums, slack adjusters, air bags, electrical, air lines and tank. The whole rear section of the trailer was replaced. There is a picture of the stainless steel frame. We also have a maintenance folder available. One advantage of this trailer is the 5" butterfly valves feeding the discharge line. We hauled soda ash so the trailer may need to be washed. Tanker is 1550 cubic feet.
