The 2009 Hummer H3T Alpha, akin to the S-10, does well with offroading. With a five-foot bed it can accommodate up to 1/2 a ton.
The H3T Alpha, despite sharing DNA with the S-10, is more than a spruced up mid-size truck. The five-foot bed is separate from the cab (unlike an Avalanche or H2) and can accommodate a load up to a 1/2 ton, so that means a pair of dirtbikes are no problem with the tailgate down. Most important, though, are the upgrades to the drivetrain, including e-locker differentials from Eaton, and a high- and low-range transfer case.
