From http://www.canadiansoldiers.com/vehi...lemarkings.htm:
"These vehicle weight classifications did not necessarily denote the actual weight in tons of the vehicle (though for tracked vehicles the numbers often coincided.) The classifications were instead derived from considerations such as axle loading, distance between axles, and impact factor."

In other words, the HUP could at one time have been re-classified having to cross bridges with a 5 ton rating. As this was the lowest Bridge Class available, many vehicles seem to have been classified as such - maybe to simplify matters?
