Hanna Trailer Supply stocks the most common sizes of MTI steel cargo trailers. We carry everything from a 5x8 enclosed to a 8.5x24 enclosed car hauler. We order these trailers in with basic features, but we have the ability to order them in with any options that you may need. The most popular upgrades that we see customers order are a radial tire upgrade, 16” on center side walls and floor members and a slant top wedge nose. Radial tires last longer than bias ply tires and they perform better at highway speeds. The slant top wedge nose makes the trailer more aerodynamic and helps cut down on fuel consumption.

Hanna Trailer Supply NATM Dealer Committed To Excellence

When you buy a Triton trailer, Parker Performance trailer, Forest River trailer, Liberty Industries trailer or any other brand name trailer, be sure to look for the NATM decal that signifies the trailer is National Association of Trailer Manufacturers standards compliant for safety and performance.  Trailer manufacturers must successfully complete the NATM Compliance Consultation in order to be allowed to use these decals on their trailers. The decal is the only way a trailer buying customer can be certain that a trailer complies with all Federal Motor Vehicle Safety Standards (FMVSS), as each of these manufacturers must complete their compliance consultation every two years. NATM is proud to uphold and support safety standards throughout the light and medium duty trailer industry. Hanna Trailer Supply offers only the best utility trailers, snowmobile trailers, enclosed trailers, aluminum utility trailers and many more trailers that carry the NATM compliant logo for our customers throughout southern Wisconsin and Northern Illinois.
