Hummer unveiled its 2004 H2 SUT (sport-utility truck), an H2 with an open cargo bed. Like the GMC Envoy XUV, the H2 SUT features a Midgate with a power window. Folding the Midgate expands the stubby cargo bed from 3 feet to 6 feet in length. Production of the SUT doesn't start until April 30; once it does, GM expects about one-third of H2 sales to be SUTs.
