  3. Humvee and Hummer H1, H2 and H3 Forum

    This U.S. military utility truck platform departed radically from the traditional, lightweight field 4x4. The Humvee's access and sheer mass raised questions, yet the move proved practical as the Humvee met a wider variety of demands. In civilian Hummer and H1 form, these vehicles found their way to the suburbs, highways and public streets...The G.M. acquisition from American General spawned stylized and popular light and compact truck versions. This forum provides a community base for owners seeking technical and maintenance answers plus a place to share travel and other experiences!
