Sounds sort of like you bought a piece of shti. Ive got multiple 6.4 owner friends, and none of them have any issues. They are tuned and deleted ghough. Several of your gripes will not be satisfied with a cummins. I do not understand why people think thdy are the end all, be all of diesel motors. Ive drove several, and never been impressed.
As for the sob story on why you need a 10 passenger bus, I watched my mom battle back to back rounds of ovarian cancer, whjch after she was cleared kf that, 2 months later on the day of her 49th birthday, was diagnosed with brain cancer, and I watched her dwindle away to a 60lb. Bed ridden vegetable in capable of talking or moving any part of her body, mouth, eyes etc, before she died on seaster sunday. So according to that logic, my father, and my nephew, who my parents had custody of, should become permanent fixtures in any of my future families travel plans? Leading me to have to buy one of those custom pre-made 6 door super duty's from up in Oklahoma? Don't think so Wilbur.
If there was forward movement in this thread, you wouldnt hear a peep from me! Honestly, I'd love to see this thing come together, but the chopping it up and adding doors, a shorter bed, etc. is way over the top, and un-necessary as far as I se it. The dogging on powerstrokes, how weak and problematic they are;, I towed my cars all over the country with mine, over a 1/4 million miles worth, and never once felt it was underpoweed, and it never once left me stranded, or broke down. Hence...me saying you got a bad one.
Every update is about how you just took another trip, and more bitches you have about the truck, but theres no progress with the build, so it's like "well wtf do you think is gonna happen? Nothig but disappointment until you fix the problem, duh". And if you didnt go around slamming any sort of criticism you get for anything, outside of the people who just stroke your ego with how "awesome" it will be when its done.
Kinda like me starting a thread on my build with my car, and saying how disapoointing, and slow 12's on street tires is, and I am building a forged stroker motor with a f1 procharger, and looking for 700rwhp, but not making any progress with it. Then I keep coming back, and complaining about how tired I am of my current power level.
Anyhow, I am done making attacks at you, carry on with your build, and I hope you get this thing completed and make me eat my words when it is finished.
