Good old V8 gas guzzler times vs 4 WD Diesel power

1991 I travelled for for the first time for about 3 months through the US and Canada, in Los Angeles I bought this Ford Ltd Station Wagon 1978. 

I guess this was when I really got the taste for road tripping the Americas, even though it was the North of 'em only. 2WD vs 4WD some 20 years later.
