Essentially seven brands of Class 8 truck are made in the US, owned by four companies - two of them being non-US companies:
Freightliner & Western Star (also Sterling, which is now discontinued), owned by German Daimler AG... The largest heavy truck manufacturer in the world.
Volvo Trucks & Mack Trucks, owned by Swedish Volvo Group - AB Volvo... Volvo is the second largest heavy truck brand in the world.
Kenworth & Peterbilt, owned by the US company Paccar. Paccar is the third largest heavy truck brand in the world.
Navistar International is a US company.
There are over 3.5 million semi truck drivers in the U.S. Some of these own their own trucks and others work for corporation or trucking firms.

You're talking about a truck classification exclusive to the US... of Class 8 truck manufacturers in the US, Peterbilt, Kenworth, and Freightliner still manufacture cabovers... just not for the US market, although Freightliner does appear to be reintroducing the Argosy to the Canadian and Mexican markets.
There are about five major manufacturers available here, but I'd be surprised if any of their units are actually made in the US.
Typically, between 44,000 - 48,000 lbs. of cargo, under US weight limitations.
