Allis Chalmers M7 too content welcomed too. Tucker did some
of the prototype work on the T26 E1, E2, and E3 Snow Tractors. Allis Chalmers
finished the development and produced it. Besides, lots of people have
both (like Lyle Van Wert) or have one and are trying to buy the other
(like me) Saginaw Products made the M19 ski / wheel one ton trailer that was normally seen two at a time behind the M7, though my M19s are towed by the Tucker via a drop hitch.
