Just been across bothe the Plenty and Tanami (east to west). If anyone interested, east end of road pretty good and loved our overnight stop at Tilmouth
Well (fair diesel price too) but once you cross into WA (they must be ashamed of it as the "welcome" sign is missing) the track conditions, including corrugstions and pot holes/bull dust, are far worse - though just tolerable for a decent off-road van and vehicle, with lowered pressures and speeds.
Anyone considering including Wolf Creek should be aware that the corrigations are horrendous on the 20km track in - an interesting sight but only worth it if you are keen to see an impressive meteorite crater; there are more picturesque sights to be seen.
