Love the H1! The only REAL HumVee. No relation in any way, shape or form to the total sh!tbox H3 that posers and wannabe's drive.
As long as it has been retro fitted with the 6.9L TDi...the 6.2L was gutless.
The A/C works overtime in them and even then, the cabin is still quit warm because the transmission sits between the driver and the passenger.
No ADR issues - there are quite a number of them on the road in Australia.
