Ah, ok, I didn't realize there was such a thing as a seven lug wheel on the later model F250s.
Although now that I'm thinking about it, I remember my brother in law had an F150 (2001 I think) with six lug wheels which we jokingly called a 5/8-ton.
The "standard" F-150 is actually the 5/8 ton. It was made in the '70s as a heavy-duty half ton (to get above the EPAs GVWR limit requiring catalytic converters).
Similarly the "light duty" F-250 is the true 3/4 ton. The F-250HD was a heavy duty version in the early '80s to get above the raised GVWR limit.
Of course the F-100 (true half ton) was discontinued. And in '99 the standard F-250 (true 3/4 ton) was rebadged as an F-150 (called F-150 7700 for its higher GVWR, and still with 7 lug wheels). So your brother-in-laws F-150 was likely a 3/4 ton.
Now the F-150 is either a heavy-duty half ton (5/8 ton?) or a 3/4 ton, depending on how it's optioned, and the F-250 is only available as a heavy-duty 3/4 ton (7/8 ton?). But the real bottom line is that the "ton" ratings mean absolutely nothing anymore (if they ever did).
