We like to think of the BridgeMaster as a Ford F-250 and a Conventional as a Hummer. The BridgeMaster in a 40′ (not 41′) has the longest bridge in the industry for a trailer in this category. This 80,000 GVW unit at 16,900 lbs., and its long bridge, carries the most weight legally, vs. any framed or frameless trailer in the market. About 45K lbs. The Conventional at 22,500 lbs, can be over permitted to 102,000 lbs.so it can carries 40K lbs.+++
