When David is gardening and Lois comes to invite David to Isreal (@37:30), an eighth gen (Brick Nose) Ford F-150 is parked behind them. This scene could take place shortly before Lois' death in November, 1986, when the eighth gen F-150 went on sale for the '87 model year. However, the truck has significant paint damage on the hood and yellowed headlights which a brand new truck for this scene would not have. A seventh gen F-150 would more accurately fit this scene.
