That guy learned the hard way that "restoring" a truck that's not running is expensive. But, I'm guessing he didn't know what he was doing. Instead of starting with a motor home he would have been well ahead to start with a truck w/a 460 in it. That way he would have had the bits and pieces he needed, like perches. And for that matter the seat belt. And radiator, and, and, and.
Then there's the 3.5 MPG. There's something seriously wrong with the engine or fuel system to get that. Big Blue got 11.0 - 11.5 MPG on the highway at 65 MPH running the A/C. And his engine was seriously worn out.
