Welcome to this great Forum and congrats on the new Monty
as far as the F350 for sure stay anyway from ANY 6.0 liter Powerstroke and the 6.4 is questionable as well, they can be "bulletproofed" for a few grand and made good but why bother but if you can swing a 2011+ 6.7 Powerstroke f350 by all means Jump on it they are great and this is coming from a Loyal Duramax/Allison guy
