I appreciate the feedback. I will never claim to know it all and rely on reliable sources (not just a google search) for education. Fortunately, we come from a Ford family. In-laws are Certified Ford mechanics (and also does hometown races). We told the Ford dealer what we were looking to do and they worked with us to make sure we had the right vehicle. The TC dealerships are covering their butt, and I understand that. The former 2008 F250 4wd definitely was not a candidate for many of the TC were available. A few refused to sell us a TC because the former F250 was not certified even though it had enhancements.
The tires (based upon my BIL - Ford dealer repair dude)are suitable and do not need to be replaced. But down the line it will be good to upgrade.
This is not our first TC. We had a 1997 real lite on the 08 F250 with the enhancements. Though we only used that one for three years. So I would not say I am a seasoned TC owner compared to TT.
Thanks for the feedback. I will continue to do my homework and welcome constructive feedback.
