Is there a thread for Truck Manufacturers?
No, but in the same way people had asked about wheel manufacturers, the list is either well hidden or very short.
Sure some places have their own production facilities, but others seem to keep the actual location or information very much under wraps.
Indy - NHS - facility in China, ex Ermico in SF.
Venture and Thunder - DLX - moved down to Mexico, maybe part of BBS or something similar, also ex Ermico SF.
Ace - always been made in China.
Almost every other truck manufacturer now is in China too, but exactly where, it is not quite as well known as woodshops.
Maybe Excel also makes trucks?
Did DSM also make trucks and other things all under the same roof there too?
I just don't know.
