Aktually they were considerably lighter than their long-nosed counterparts. Shorter wheelbase contributed to this but also made them ride noticeably crappier than the alternative truck layout.

I didn't mean gross weight. I seem to remember something about how the axles weighed out that made them very sensitive to popping for a heavy axle. I might be mistaken though.

Naw, you’re correct in normal applications. The steer axle doesn’t get all the weight it can legally carry so a truck that legally could haul 73,280 or 80,000 lbs would have to deduct the steer axle’s deficit amount off the gross it could legally carry.

Not true if some of the load was carried forward of the fifth wheel (piling cantilevered over the cab for example).
