The new 7.3 is a beast on paper, no doubt.
One of the reasons we expedited our purchase new in 2019, after many years of lollygagging, is because we were worried the V10 would disappear in 2020. That fear pushed us over the edge. The V10 was proven reliable in the long term, with cheap parts, cheap maintenance, and plenty of power for Class C. So we upgraded.
The 6 speed trans was more recent, but it is used in rigs with much more power than the V10 and much more GVWR and GCWR than any class C I would ever purchase.
I went with the proven reliable V10 and 6spd and have zero regrets. I'm sure the 7.3 has a good bit more performance, but additional performance to me wasn't worth the risk with less-proven equipment. Just my opinion and I don't know anything about anything.
What Pat said sums up my thoughts. If I were in the market for a brand new rig today but could continue with what I have for a year or two longer, that would be better. I would feel more comfortable with a 2022, but better yet a 2023 chassis.
