Yes Sir’ the trucks we used were manufactured by Rite-Way, they were three axle and carried a max of 10yd’s.
And it was from 1973 until 1981 that I chased around a muck rake, I never seemed to catch up to it though… 
My Daddy used to tell me that it came to concrete work the only easy part was parking you truck on it, the rest was damm tough.
Good luck with chosen career
