"no load" registration
Similar situation in U.K., my Deuce is registered as a historical vehicle built in 1959, which allows it to be excempt from road tax and ministry test, but not allowed to carry a load, although some of my group carry spares and camping gear, it can also be driven on ordinary car license, as long as they were built before 1960. Thats why most military vehicles over here are registered as 1959.
If you are involved in an accident, and the ministry finds a mechanical defect, they really jump on you. its the old story, everythings o.k. ,till something happens then the s..t hits the fan!
I,ll post some numbers of my truck i,d like to know what year it really is!
