The H1 generations we buy
The H1 was the civilian version of the military Humvee, sold from 1992 through 2006 in wagon, pickup, and open-top forms. Early trucks used the 6.2L and then 6.5L GM diesels, with the 6.5L turbo diesel — and a rare Duramax-powered Alpha for 2006 — at the top. Everything about it is oversized: portal geared hubs, a central tire inflation system, and the width of a dually. It was never a volume vehicle, and surviving trucks trade in a collector market of their own.
The H1 in San Diego trades on specification and completeness: state the engine (the 2006 Duramax Alpha is the prize), the body style, and whether the geared hubs and tire inflation system work. Honest rust and underbody photos matter more than a wash — these buyers look underneath first.
