As much as I hate to do it I am selling both my trucks. One is a single axle 1978 U685T model converted to a dump. The other is a 1977 DM685S tandem axle dump. Both have an ENDT675 engine. Both run and drive and are ready for work. They both have air to the rear for a trailer. The trucks are in good shape for their age. I have all the paperwork on both from the Mack museum. They need a good home with someone that appreciates the history they represent. If interested contact me on the forum and I'll supply pictures and answer questions. The trucks are located in NE Pennsylvania. Price is negot
