Silver Eagle M11 · U.S. Army Cargo Trailers
Mil-spec is a requirement, not a phrase.
A field-grade cargo trailer engineered to U.S. Army specification — manufactured on the same Portland floor that has built Silver Eagle equipment since 1933.

Where the M11 fits
Every spec documented. Every weld traceable.
The M11 is engineered to meet U.S. Army cargo trailer specifications. Every chassis component, every weld procedure, every coating step is documented and traceable. That is what mil-spec actually means.
Same Silver Eagle factory floor that has been pulling for the U.S. Army for decades. The engineering team that draws the M11 walks twenty steps to the welders who build it. The procurement officer specifying the M11 is talking to the same team that certifies the weld.
How it's engineered
DOCUMENTED PROCEDURE
AWS D1.1 certified welds with welder on record.
Every weld on the M11 is made to certified procedure by a documented welder. Traceability is part of the build, not an after-the-fact paperwork exercise.
PROCUREMENT-GRADE
Built for the paperwork your officer has to file.
The certifications, the documentation, the chain of custody — engineered into the build process from the start, not bolted on at the end.
GALVANIZED OPTION
For environments that destroy E-coat alone.
Galvanized frame option available for operating theaters where the 11-stage E-coat alone is not enough. Mil-spec topcoat over a galvanized base for the harshest environments.
Trusted by
