I doubt he parked on the side of the house as a courtesy. (Especially to his own family.)PF was not a visitor to the place. He was a resident. It is a western courtesy not to block the guests in with your vehicle. SF2 might not know that. He was twenty years of age when SF1 bought the place, so it seems unlikely that he ever lived in the country. JMO
He had the tote in the back of the truck, likely with Kelsey's body in it.
He didn't want to risk anyone seeing it or asking about it.
Imo
