I hear you on the 2019 and mine will be my daily driver as well and will spend 95% of it's life on pavement. I'll have to check with the dealer today that's getting back to me on the 18 price to see what he will do on a 19. Only issue with that is "He said they don't plan on scheduling the first retail orders to be built until mid November. That would put the first retail orders produced hitting lots at the end of January or more likely, sometime in February. If you weren't lucky enough to be allocated one of the first built 2019's, however, you would not see the truck until mid-March or April".
Part of me says just keep F250 that already has Carli Pintop 2.5 kit and upgrade that kit and do some engine mods and drive it until it falls apart. However, after getting a new engine at 66K I just don't have a ton of trust in it.
Decisions, decisions not easy when you over think/research things. The Raptor ride would be so much better.
