This is a hard one for me, had a bunch of first trucks.
1978 IH Scout II, 345 4 barrel carb. Had it jacked up for a short time until it just suddenly decided to start rolling over. Did that twice and dad decided it was cheaper to drop it back down than keep fixing the body.
Drove his old company truck for awhile, 1980 Chev 350 with a Clarion cassette deck. It was fast for a stock truck but the bench seat is what I remember the most about it. Lot of memories made on that seat.
