Wow, awesome reading. I appreciate all the info from everyone over the years and surprisingly very friendly exchanges.
I just sold my 2008 6.7 with deletes. Only had 100k but was starting to have some issues here and there that was going to start costing some serious cash. Combine that with new truck envy and here I am. Had an 03 5.7 1500 years ago. Liked the truck but hated it for towing. Sounds like the 6.4 has major improvements over that. Test drove one with 3:73 and loved the truck! I loved my diesel especially towing heavy, and would like another one but it just doesn't make sense for me. I go Missouri into CO and over some passes once a year. I never tow more than 10k usually less. Around here my wife tows her 3000lb bumper pull horse trailer and a single horse. Like many on here, pencil to paper the gas engine is best suited for my needs and pocketbook. I've been on both sides of gas vs diesel, these new diesel trucks are down right scary to own outside of warranty. Add to that fuel filters, higher cost fuel and potentially fuel additives, 2 batteries, urea, wear & tear on suspension components and tires, if not deleted then EGR cleanings, 9k higher cost, etc... If I towed heavy even once a month for much distance at all it would be worth it, but I don't.
So I ordered a 2018 6.4 Big Horn 4:10 Sport Appearance (BLK wheels), Luxury Group, Off road package, and the 8.4 stereo in bright white. Got the VON # today. Some of the posts down right scare me on here, but go type in ford 6.2 tick. Or ecoboost blown head gasket. Forums are filled with those who are addicted to knowledge about their machine, and those that had s*** go wrong and need answers or just want to complain about it. I don't see any more issues with these than anything else really.
Also as an update, they did another Ike Guantlet with a power wagon. 9k behind it. Went right up the pull at 60 MPH. Was floored some but some lifting here and there. That was some redemption in my mind especially with the heavier tires. I don't go over the Eisenhower, but hoping the passes I do hit give me similar results to their last pull. Will make some updates when it shows up and I drive it.
