What do I trust?

Have an Outlook Monitor which I've included the fact in the trucks profile that it has 35's to make the neccesary changes to display an accurate speed as I'm aware that my speedo will be off slightly (+ or -), not sure. My GPS however, which should be "impartial" is showing my speed about 6 mph less than the Outlook's indicated speed. Any thoughts as I would really like to avoid tickets if possible..Many tks!

I would tend to trust the GPS but if you want to be sure to avoid ticket use the lower of the 2.

Yeah I have pretty much same set up as you and I just got a ticket but I was pretty surprised my speedo wasn't off at all I thought it was a bit weird
