Hi Barefoot XR6,
All XG,XH and XH II utes are called Longreach. When the XG was launched this was the name given to the utes and pano's. XG/XH were available in GLi and S pak trims, with XG having XR6 and the XH XR6 and 8 models as well.
The XG and XH also had a model called the OUTBACK which had the big tyres, diff and crash plates underneath. Iam also pretty sure they had long range petrol tanks, which was just another tank bolted up beside the standard tank.
