I drove my stock '78 FJ40 from Colo Springs to Michigan in 1990 - along I-80, then up through upper Michigan and down thru Wisconsin and back on I-90. About 4K miles. Very tiring. Headwinds hurt gas mileage. Had to readjust timing due to spark knock (lower elevation) in Nebraska. Brought gobs of spare parts, but needed none. Had an exhaust donut gasket installed in Michigan. It was June, so it was 106 degrees F. in Omaha, and about 120 in the cab of my truck. It made me very sleepy. Memorable event: getting a warning from a Nebraska trooper for going 59 mph in a 55 zone. What a putz - but a speeding ticket in a '40 is always a trip. Had a blast - saw a few other FJ40s (all in Michigan, oddly - including an FJ45). I drove exactly 60 the entire way - on 235-75-15 tires - didn't want to push past 3000 rpm. I used lead additive along the way, since it was all hard, highway miles. Enjoy the ride!
