I have found a couple of articles that indicate that not all the M715s came with a hand throttle, mine did. More than one sorce said that if the truck was a radio truck it at least had the hand throttle to keep it revved up if not also a 100amp gen, not the standard 60amp. No indication mine every had a radio but I did find mine with a heater/defroster (appears stock) and an artic top. Any thoughts???
