That should be a really nice work truck. The 2001-2002 8.1L/NV4500 was way the best. They have the really hard to find high mount air conditioner brackets. That is really low miles. Low mile good condition ones are really hard to find. The 8.1L are really hard to find also. They are nearly always beat to pieces.
The 2000 454/NV4500 that I have is the nicest one I have seen in a long time and it has a little over 100,000 on it.
