It is a 1979 Ford F350 Creger. Not much is known about these, in fact i haven't been able to find much about them myself. Tales from rumorville said that you had to custom order these from Ford, and they sent the cab/chassis to Champion homes to build the RV. Its wonderful and perfect for me, 4wd, 400m, c6 tranny, dana 60 front and rear axles.
