Not using all my horses by design??

If you are running a PTO implement, you'll have to run PTO speed regardless. I assume it doesn't have 540E PTO like some tractors do, so you can actually get 540 PTO while at a much lower engine RPM?
I can run 540E on my tractor, use less fuel, and have plenty of hp... But without it, I still have to run 2500RPM to get 540rpm from the PTO, whether I need the power or not.

48hp and I burn 1gal/hr

I don't beleive it has 540E. However to turn the engine with a low load at the appropriate rpm would still be less fuel I beleive then fully loaded. That said, I still am wondering if there's a fuel advantage to doing that and or a longevity por/con to running like that.

Does having too much HP potentially cause problems if you run the engine at a lower rpm because you don't need all the HP and maybe then have more regen issues?

I have ZERO regen issues because both of my tractors are pre 4 and I'd never buy anything else any way.

I rarely run either of mine at 540 pto speed actually and one of mine is 540-1000 and I use the 1000 rpm 21 spline pto stub to run grain legs and such.

I'm not sure if that is to me or not. The HP is rated at 108. I am not mistaking that for torque. The peak torque is at 2206rpm on this engine, but I forgot the number.

With that, my use range would be significantly lower as I don't need that much power for pretty much anything I'm going to do or use.

No that was not for you specifically. That was for new tractor owners who fall into the siren call of HP. If you are paying for a tractor JUST because of HP its a good idea to make sure that HP is made at a reasonable RPM.

The HP trap is real!

Most of my implements and plan to purchase implements need about 40 to 50hp. Hence the question, run a 60hp tractor flat out all the time, or barely work a 108hp tractor.

With a new emission diesel engine, you are better off to buy "just enough" horsepower and run it hard. Or you will be doing lots of regens.

At around 75 HP+, most (all?) tractor diesels need DEF to meet emissions, so that is another layer of cost to weave in.

Regen: where you burn more fuel to attone for the fuel you have already burned in order to reduce emissions on small tractors which have virtually no impact on the environment. In the grand scheme of things, there are simply too few in operation for too few hours and widely dispersed for all of the effort to do anything more than make someone think they are 'helping'.

What all are you wanting to do other than mow?

A Ventrac was built for mowing steep hills and it can do may other tasks well. It comes in gas or diesel.

There's no DEF or regen cycles as far as I know.

Till, disc, hill, pull some big lumber here and there, operate a BH100, and not mow.

I also have to construct my camp with it. Gravel, holes, digging power/water/air lines, moving stuff, leveling dirt etc.

If it's new and 108 horsepower like you say it is, it will have both SCR and DEF injection.

Starting to think you are blowing smoke.
