Must Have Been A Beer or 12 Involved

In 86 or 87 I was in a Ford show room and saw an F250 with a semi-floating axle. I was shocked. It was not available with a diesel or 460 and they kept it around for about 10 years. I thought it confused things since I felt semi floating rear ends belonged on cars and 1/2 tons, not on the heavier trucks.
I feel that semi or full floating is a dividing line between 1/2 ton and 3/4 ton.
