Thanks. I've been on the F150 on line forums for a few months and there's alot of good info there. That's how found PHP. I'm strongly leaning towards the Gryhon, But as I said, it's all so confusing to me. I need the added programming because of my mods. And of course the added benefit of "More Power" is very nice! I'm already getting great mileage, but a couple more wouldn't hurt either. I like that I can leave it on the dash and change from regular driving to a "tow" mode when I've got my Ranger in tow. One thing I like too is that I can maybe get another rearview camera, and put it on my enclosed trailer I use to haul my Ranger. It would be a big aid in backing that thing up. It sounds like this may be the place to be. I think I will make a call to Bill next week. Thanks again!!
