I spoke with Malone and the Malone MegaSport Kayak Trailer part # MPG535 is USA made and assembled save for the leaf springs and wheels/tires.

The trailer does have a five year warranty on the other hand so if anything were to go wrong with those parts then you would be covered. view full answer...
