Coincidence? White pickup parked in front of Farmhouse where the Curriers were killed?

Since finding this podcast and finding out I live 3 miles down the road of the farmhouse and drove past the site almost daily. I poked around and found a listing on realtor.com listed before the Curriers went missing and there is a white pickup parked out front in the pictures the realtor took for the listing. Is there any info about him driving his work truck cross country or the timeline in which he knew what house he was going to use for crimes when he buried a kill kit here?
