Going back to gasser based on needs (need advice)

I think going from gas to diesel, brings the biggest smile, when towing. You seem to have already convinced yourself, that you'd be happy with a gas engine, so I say go for it!!

My Ford 6.2 does a good job for me, and If needed, 4K rpm to pull a hill, is very smooth, and not a screaming sound. I've no experience with the 7.3, but would expect the same as mine.

As suggested, take a test drive.
