Looking for other suggestions...

It's a gas water heater. City water supply. Usually, my morning
shower lacks enough hot water...it'll get tepid after a few minutes
where I have to shut of the cold completely. A couple of times I even
shut off the cold before I hop in and it's still only barely warm.

Nobody else is using the water and there isn't any timer or anything.

I have drained the hot water tank. And, yesterday, I thought I'd
replace the dip tube, but I pulled the old one out and it was in
perfect shape.

So I'm down to a bad thermostat?

You do know they make those little restrictors that limit the amount
of water that a shower uses?

If you are not willing to go that route or take shorter showers,
then a new larger water heater will solve all your problems.

There are no other solutions.
